Ask Sal Anything! Homeroom - Thursday August 27

Hi everyone, Sal here from Khan Academy. Welcome to the Homeroom live stream!

Today, we're going to be doing an ask me anything about anything. So, if you have your questions, start to put them in the message boards underneath this video on Facebook or YouTube. We have team members who are going to surface the questions to me, and uh, feel free to be very creative with your questions. I'm happy to—I’m hard to offend or surprise.

But before we get into that, I will make my standard announcements. First of all, a reminder that Khan Academy is a not-for-profit organization. We can only exist through philanthropic donations from folks like yourself. So, if you're in a position to donate, please think about going to khanacademy.org/donate, and any amount—ten dollars, twenty dollars—it all makes a difference. It allows us to provide a free, world-class education for anyone, anywhere. At least be part of that.

The other announcement is, you know, I want to give a special shout out to several organizations that have helped Khan Academy, especially through the COVID crisis. We were already running into deficit before the crisis, and then our server costs have gone up dramatically because our traffic is almost 3x of what we saw during normal times. We've been trying to accelerate content areas and various programs for teachers and parents. So, special thanks to Bank of America, Google.org, AT&T, Fastly, and Novartis, and many others, Amgen Foundation, many other foundations and organizations that have supported Khan Academy over the years but especially during the COVID crisis to make sure that we can support all of you all as much as possible.

Also, I want to make an announcement: if you've enjoyed these live streams, you can also access them as a podcast. I think a subset of them maybe edit a little bit as a podcast, and that has the benefit of you not having to see my face, which might be more pleasant, and you could drive. So, I encourage you to take a look at that!

I see the questions starting to come in. Before I start getting to them, I'll make a couple of announcements just in case you all don't know about it. Since we are into the back-to-school period, Khan Academy has a ton of resources for you. Hopefully, you're aware of—we have pretty much every subject in grades starting from pre-K through the core of college. We have Khan Academy Kids that goes from a three-year-old to six or seven-year-olds, and that's reading, writing, math, and social-emotional learning. Everything I'm talking about is free, not-for-profit, paid for with those donations, which hopefully some of y'all are making.

We have math that obviously goes well into elementary, middle, high school, and then college statistics, calculus, and even multi-variable. We're about to launch a multi-variable calculus that has exercises in the next couple of weeks. We've also launched something called "Get Ready for Grade Level" courses. This is an issue that's always existed but it's frankly a bigger issue now because of COVID that, as kids come into the new school years—how do you know that you're ready for whatever course you're getting into? You can go to the "Get Ready for," let's say, sixth-grade course or the "Get Ready for Algebra" course, take the course challenge. If you do well on it, that means you're pretty much ready. If you don't do well on it, then you can finish and get mastery on that "Get Ready for Grade Level" course. It'll accelerate you through the stuff you know by taking course challenges and unit tests, but the other stuff you can make sure you have a strong foundation, which you can do in parallel to the grade-level course or you can do before so that you have a really strong foundation.

Another project I want to make sure that everyone knows about before I jump into the questions is a side project that I hope one day might become part of Khan Academy, but today it is a side project. It's called Schoolhouse.world, and this is a place where you, as a student or your children, or anyone you know can get free live group tutoring from really, well, from accomplished and really good tutors of frankly all ages. If you want to be a tutor, you can also apply to be a tutor, and right now we have more tutors than students. So, there are actually several thousand slots where you can get free tutoring, especially starting in high school math and then in the next few weeks we’re probably going to expand to K through 12 math, the sciences. We're also doing SAT and math now; we'll probably do SAT tutoring in English in the next few weeks as well.

So, of any age, if you're a parent of a younger child, say 13 or under, you would be the person who would have to go register on schoolhouse.world, but encourage as many folks as possible to go there. You can kind of get on the waiting list, but there are a lot of openings for several thousand folks right now to start getting some free group tutoring sessions live.

So, with that, I'm happy to start taking some questions.

Let's see from YouTube: 80videos, there's actually two questions. How can we get interested in studying on our own? And 18videos is also, what are the easiest ways to get interested in math?

Well, um, I'll try to get you interested right now. You know, every subject that you look at in school—sometimes when you're in school you're like, “Oh, this is being forced on me! I have to do this for the test.” And when you think of it that way, it loses its joy. But when you appreciate that, as sentient beings in this universe, one of the things that makes humans, humans is that we’re trying to understand the universe we’re living in, and we’re trying to understand how do we interact with this—society in the universe—and have happy, productive lives. Knowledge is really the underlying thing that gives us clues about the mystery we’re in and how we can interact with it.

The things that you see in your textbook or on Khan Academy or wherever else—this is human knowledge that has been accumulated over thousands of years. People have often dedicated their entire lives to one paragraph of your textbook, and you get to just see the answer, the solution, or the understanding right there. So, as you read your textbook, or as you learn in class, or as you're on Khan Academy, remind yourself how lucky we are to have this knowledge.

And then also, never be satisfied with just memorizing the formula or figuring out how to pattern match for the test. Always think about how this connects to other things that I know—how does this connect to my understanding of the universe? You know, when you're in chemistry class and you’re learning about atoms and you know electrons and protons and neutrons, realize, wow, these are mental constructs that we, as human beings, have formed to predict what happens when these substances interact with each other in different conditions. But what really is an atom like? You know, if we can't see it, if we can't touch it, we can measure in indirect ways—what does that really mean?

And, you know, what is real? If an atom is mostly open free space—if most of what we see around ourselves is actually vacuum and what I think is solid is actually really coulomb repulsive forces between atoms that don't want their electrons to overlap with each other—when you start to, you’re like, wow, this is starting to explain the philosophy of the universe. You know, you can do that in any science. The humanities give us clues about the human condition and who we are as beings.

Math, you know, there's a special place for math where that’s the purest way of understanding the universe. If we ever come in contact with aliens that try to communicate with us, math is going to be our initial touchpoint where we are able to establish that the other party is actually a sentient, intelligent being. Probably, with math, we'll try to, you know, give them prime numbers or something like that, or they would give us prime numbers to see whether we’re actually intelligent or some other type of universal mathematical problem.

So, you know, I find math to be the purest, most abstract. Everything else is kind of clouded by our senses. You know, even things like physics and other sciences—it’s really all that we can perceive and measure. But math has a purity to it that gets kind of at a much deeper state.

And, you know, there’s definitely some concepts out there in math that I generally think will blow your mind. Many of y'all have seen that video where I talk about Euler's identity—where e to the i pi is equal to negative one. That's one of those things that just gives you chills when you realize that e comes from notions of continuously compounding interest, the derivative of a function that’s itself—it comes out of some natural phenomenon—exponential growth. Pi, obviously the ratio of the circumference to the diameter of a circle. I is a number that in some ways is constructed by mathematicians to have what could be the next square defined as the square root of negative one, and the fact that there’s a very strong argument that e to the i pi—these things that come out of completely different domains equals negative one—it’s chilling!

It’s like there’s some hidden pattern to the universe that we’re just getting glimpses of. You know, some people have called Euler's identity proof of the existence of God. You know, I’ll leave it up to you to think about whether you feel that or not, but I'm just trying to make you appreciate that, you know, the tools that you’re building in math class are going to open up a universe that will give you—that will be awe-inspiring, and they will give you skills that will help you be productive and useful in life, and hopefully be able to support yourself and support those you care about, and make a dent in the universe.

So anyway, long answer; you’ve triggered me in a good way. See other questions from YouTube. Vincere Gaming asks, when did you really start to love learning?

You know, I— as you can tell from my answer I just gave, I love learning! One of the reasons why I love my job is a big part of my job is I continue to make content, and I continue to learn new things so that I can really intuitively understand them, connect it to other things I know, and hopefully communicate it to y'all in ways that are useful.

In other parts of my job where we're growing an organization, we’re building software, we're creating new content, we're figuring out how to build awareness for what we're doing—there’s also learning that I get to do with really great people who teach me, and I get to learn from experience as well. I would say, you know, early on in my schooling it was kind of hit and miss. Certain classes I was naturally excited about, and I think I was lucky to have some really great teachers, and then in other classes, they didn't resonate as strongly with me from an early age.

But then by the time I got to high school, especially college, I started to appreciate how everything connected and how empowering all of it was. Then I realized that, you know, some of that learning that I was doing for fun even outside of school was really connected to the learning that I was doing in school. So I think it’s been a journey for me. I think maybe when I was in my late teens that I really unabashedly became someone who would very openly say that I love learning because I really do think it is the most human action we can do. You know, we've been given these 100 billion or so neurons for a reason.

So, from YouTube, another question from Vincere: actually, there are two questions here from Vincere. How should you prepare for a test? And then from Nikhil Govinder: I hope you're well. I'm doing great, thanks Nikhil! What are the best studying methods or techniques to get a 90 and above percentage in high school?

So for the best way to prepare for a test, it's to be thinking about the concepts well before the test. And look, I’ll say this as someone—I still am a procrastinator sometimes, but when I was young—a teenager in college—I was a procrastinator. So I’m not going to judge any of you who are cramming for late-night exams or, you know, trying to learn as much as you can staying up all night. But I will tell you, as kind of Uncle Sal, that is not healthy.

And I’ve learned—if I were to do do-overs—if you just kind of, you know, do a reasonable amount every day, and while you're doing it, just don't pattern match and do it robotically. Really ponder it—think about what you're working on—by the time the test comes around you're going to say, oh, this is intuitive because your brain will have had a chance to really marinate in the knowledge.

And you know, the one thing I will tell you, and this is a skill that I learned actually in college—you know what I had a degree in? I majored in electrical engineering, computer science, and another in math. In some of those theoretical math classes, you know, you look at the problems that you’re given in, say, a topology class, and you're like, okay, I understand the problem, but I have no idea how to approach this problem.

What I found is, if you give your brain the problem, think about it for a few minutes, and then you kind of delegate the problem to your subconscious and maybe even sleep on it—literally sleep on it—that the next day, all of a sudden, your subconscious passes you a memo like, hey, this is the answer! You’re like, oh, okay, yes! Now I can do that topological proof.

And so I learned in undergraduate, you know, essentially having challenges like this—that we have an incredible, you know, our consciousness—the part that we strongly associate with—is just a small part of the horsepower that you have, and I truly believe everyone has. I mean, these hundreds of billions of neurons that we have working for us.

So, you know, learn to trust and delegate. The way that you do that is you prime your brain; you take the knowledge in, you read it, you try to get it, you may watch a video to try to get some practice. Maybe some of it sticks, maybe some of it sticks enough to do the problem, but you still don’t have a strong intuition yet—let it marinate! If you don’t know how to do the problem, let it marinate! You'd be surprised, 24 hours later, all of a sudden, you know how to do it.

Now, what I just described is not a great technique for cramming because it takes a little bit of a leap of faith, and sometimes it might not hit for 24 hours or 48 hours. I’d be surprised if it actually takes longer than that, but it’s all about creating a habit of learning in whatever subject. Regardless of whatever time frame you’re doing it—whether you're doing it in a healthy, you know, regular way, or whether you're cramming before a test—always try to draw connections. Always try to just, don’t assume that A leads to C. Say: Why does A lead to C? Is it because it leads to B first? But then why does it lead to B?

Talk to people about it, have conversations about it, and that conversing about it—also another way to draw connections. You know, I will say that—I’ve always been skeptical of actually group studying. You know, sometimes studying is a solitary activity, and I actually think you should—sometimes group study is kind of not as productive as you would like. So I would always say your first goal should be you and the material, digging deep in it.

But then once you’ve both had a chance to kind of struggle around with it—then I think having conversations could be really good. The other thing I would say is just get in the right frame of mind. I think for a lot of folks just the stress and anxiety associated with tests become the thing that makes it hard for them to take the test or do well in the test. And so I highly recommend meditating.

We’ve actually made meditations on Khan Academy. You know, recognize that your life is so much more than a performance on any one test—that, you know, a hundred years from now, no one's going to care how you performed on one test or another. So, you know, just keep that in mind—that, you know, a test—it’s important to be prepared, do your best, but be in the zen state as you take it. Don’t be all caught up of like, what’s going to happen if I do badly on the test, or I have to do well if I want this to happen. That’s going to be counterproductive.

Let's see. There’s a question from Facebook. Lisa Wiltrout asks, what platform do you recommend to learn science terms for long-term memory? Is there an existing flashcard site?

So, you know, for flashcard-type stuff there is Quizlet. I recommend it. I’m good friends with the founder of Quizlet, and I’m sure there are people who've already created flashcards on Quizlet for whatever you need to learn, and you can also create your own flashcards. They have some really neat modalities where you can, you know, have kind of flashcards.

But there are other ways to make sure that you've essentially memorized the knowledge. I would say Khan Academy is a great place for practicing the skills and concepts of science, and a little bit of the—not the knowledge, I guess you could call it memorization if you like. So if you go to Khan Academy for biology or chemistry or physics. Chemistry and physics don’t have a lot of memorization. I would argue even some of the formulas—once you understand the intuition behind them, you don’t need to memorize them.

And you can see it, and you can even derive some from some of the others. Biology has a little bit of memorization, but once again it’s more conceptual. You know, in some classes, you might have to memorize the phases of mitosis or meiosis, or you know, things like that. But I think Khan Academy really has your back. And you know, fingers crossed, I’m hoping that in the next few months we have the resources to really flesh out a middle school and early high school science on China. We actually have high school science already, but we’re going to take that to the next level.

So, you know, stay tuned! We already have a lot of science on Khan Academy both high school and AP level—chemistry, biology, physics—and we’re building out more of the high school. Hope to have middle school soon and obviously we have college level because the AP and the college level are essentially the same day. And we also have things like econ. So, check out Khan Academy, but Quizlet is also a great place to make sure you memorize your facts.

So from YouTube, Susanna Garcia Dominguez— and Susanna, I feel like I know you because you are a consistent strong question-asker on these. I don’t even look at the question when I have a guest on, and I see this from Susanna and I'm like, that's going to be a good question. I'm just going to read it before I even know what she's asking.

So Sal asks. So Susanna asks: Hi Sal, you’re such a happy person, but do you have any pet peeves?

Well, I’m happy that you think I’m a happy person. And look, I do think for the most part I am a happy person. But I have my share of, you know, every now and then—I've talked about this, you know, I've been anxious on planes. I’ve learned to deal with it. Actually, that’s what brought me to meditation, which has actually made me a much happier person. Because it is easy, especially when you feel like you’re working on something really important— you know, I feel like Khan Academy—we’ve got to get this right—there are millions of folks depending on us.

And so sometimes at work if, you know, people are disagreeing with something or something didn’t happen the way that you wanted, you know, you might get a little triggered or you go home and you lose sleep. You wake up, you’re like, oh, how come this can't happen faster, or why did that person say that?

And, you know, I’ve learned through meditation to not even let that happen. You know, it’s important to engage on a problem and do what you can, but then you need to compartmentalize that a little bit and not let it affect you, and not let you mull on it. And until a lot of times I, you know— to the previous question, I delegate it to my subconscious and let my subconscious say, you worry about it; I gotta sleep. Usually when I wake up the next morning or the, you know, a week later, you know, the thing that I thought was this problem that could have kept me up—there’s usually a solution! It usually resolves itself, or come up with the solution, and you realize, yeah, that was a silly thing to stress over.

So once you go through enough cycles like that in life, there are many things that in high school, college, you know, I stressed over well, I— you know, I’m sure a lot of kids are stressed about college admissions now. You know, we all had our childhood crushes—does that person even see me? Do I have the guts to walk up to them and talk to them? Will I pick the right major? How do I make friends? You know, fear of missing out, can I pick the right career? How am I going to pay off my debt? You know, these are all stresses and anxieties—did someone say that about me?

But that’s not who I am! I’m really a nicer person than that. And, you know, over time you just realize that these things that stress you out a week later, six months later, really aren’t that important. So when someone new comes up, you’re like, you know what? Six months from now, if something needs fixing, I’ll fix it. If there’s some action I can take that’s productive, I’ll take it. But don’t let it bother you, and meditation really helps there.

Because meditation, you know, our minds are normally just all over the place. You’re like, you know, I wonder if a horse in a breeze—a zebra can breed? Oh, I gotta pay my taxes! Am I a good father? That’s like five seconds of your brain. If you just let it, you know, could I outrun a bear? You can’t!

You know, even those big, you know, chubby bears—no, you can’t outrun them! You know, so your brain is like a circus; it's all sorts of stuff is going on from moment to moment, and meditation is really getting it back to a place where you’re just like this candle without wind—you’re just still and you’re not thinking. And it's when you’re in that frame of mind, you know, there’s nothing you— you know, this can apply in any religion. You know, in every religion, there have been mystics who have gotten well steeped in meditation, and they’ve been able to still their mind. And when you still your mind, you start appreciating how silly some of the things that you were taking seriously are, and you start appreciating that, you know, at the end of the day, all you really are are— you know, you can really claim you are is a consciousness.

Even, you know, these notions of your identity and your name, and your physical persona—these are just part of material reality. These are—and some of these things are constructed. You know, your persona, your place in society, your connections—and that liberates you a little bit.

The other, um, the reason I’m happy is I think I’ve just been very lucky in life. You know, I get to do what I love. You know, I have a wonderful wife, wonderful kids. I get to, you know, work with wonderful people, and I think, you know, there’s nothing like that that, you know, I guess makes you click your heels on the way to work—which is now in my house.

Alright, so Facebook. Mohammed Ibrahim says, Sal, do you play video games?

Um, kind of! So I—I don't want to—this might create an unpleasant image for many of y'all, but I’m a big fan of Just Dance. I find it to be an incredibly good workout, and it’s kind of a type of video game that you can play and not feel guilty that you played it because it's a good workout; you can play with the kids; the whole family can play. It’s very social, so I'm a fan of that.

You know, growing up I didn’t—I was the kid, you know, we couldn’t afford a video game system really. So, I was the kid that would go to my friend’s house and kind of watch them play Nintendo; every now and then they would hand the joystick to me and I was like, no, I’m just used to watching. So I didn’t play a lot growing up.

I mean, and to something, I’m careful about them because I, you know, I think I would naturally be sucked into them if I let myself get sucked into them. And you know, I definitely need to be careful that I don’t get sucked into things like that, especially now. I mean now I wouldn’t get sucked in because I have, I’m an adult; I have stuff to do, and I have children to raise and a wife and family.

But, you know, I think there’s a danger of getting sucked into them. So, even with my kids, you know, they’re 11, 9, and 5. They’re really into Minecraft right now; we limit them to just Sunday mornings they can do Minecraft. So, you know, and Minecraft and the whole spectrum of games is actually quite good. It’s creative, etc., but it can also become super immersive, and the kids kind of have trouble getting themselves out of that world.

So, yeah, you know, I think in moderation, video games can be great, and I highly recommend Just Dance. If you're ever on the—whatever they have the global dance floor, I think my username is Khan something, so you might see me sometime on the global dance floor on Just Dance.

From Facebook, Yulia Corleva asks, do you play chess? Do you like it?

Yes, I would like to learn to play! The reason I ask you about it is just because you’re a great teacher. Oh, thank you!

So, I do play chess; I would consider myself a very good amateur. I played chess, you know, I first played when I was five; my uncles taught me to play. I never kind of played competitively. I would say, you know, I’ve had a few highlights in my chess life. There was an event at one of our funders’ house where Magnus Carlsen showed up and played a demo game against four people, and he was blindfolded. I was one of the four people, and there was a moment—and he was playing four; he was playing three other people, and he was blindfolded—so I'm not claiming that I’m anywhere close, but there was a moment where I guess his visual—because he was clearly memorizing four boards at once—he made a mistake, and I had an advantage. I had a rook advantage on Magnus Carlsen, and that actually made me nervous.

I was like, I cannot mess this up at this point! And then, like, he beat the other three players pretty quickly, and then I just felt his chess brain power completely focused on me like, crushing me. And I just choked! But he came up, you know, took the blindfold off, and he kind of came up and he kind of like, “Good game!” You know, I was nervous for a moment. That’s the peak of my chess career!

And I have to say, my son, my oldest son Imran—he's really into chess, and he has made me a lot better. We play a couple of times a week, and you know, I have to give him credit—he has a really great growth mindset about it. About a year ago I would win about 70% of the game time; he’s quite good, as you can imagine, for an 11-year-old. Considering, you know, I had an advantage momentarily against Magnus Carlsen while he was playing blindfolded in four other people.

But now, he wins about 60% of the games, and if I beat him he’s like, “Okay, give me a few hours,” and then he goes—he asks about a site he goes to the site called Chess Kids, which I think is great. You know, it’s like a four-dollar-a-month type membership. Obviously, I’m a big fan of free world-class learning, but I think, you know, that’s a good deal for learning chess because that’s really good exercises and he’s learned a lot, and I’m not on the side—but he’s making me a lot better, and sometimes he explains the new techniques that he learns on chess.

But I really like that whenever he loses he doesn’t throw a tantrum—he’s like, “Give me a few hours.” He goes on Chess Kids, and he works his skills, and then he’s like, “Dad, do you want to play?” And then when he has that look—“Dad, do you want to play?” I know I’m about to be crushed, and I’m going to have to up-level myself a little bit.

No, because I think it’s a wonderful game. Very—and you learn frankly a lot about life! You learn a lot about, you know, patience. It’s a wonderful game!

So, YouTube, Adrian Avila asks, what was your band’s name in high school?

I mean, I’m ashamed to say because I’m really not a negative person, and you know, but in high school our band’s name was Malignancy. It was a heavy metal band. We were enamored with names that sounded, I don’t know, horrifying in some way or yeah, but that was it! We actually changed the name or we were nameless for a while because there was some other band name that it was—we, you know, I was on one side this very curious academic kid, but there was a side I was a little bit angsty and angry, so I was drawn at that age to fairly extreme heavy metal.

And I was the lead singer—I guess I’d say lead screamer, lead growler. But, you know, there was a weekend where I had to pick between going to National Academic Games and performing with our band, which was our first gig. I think we were going to open for a band called Paralysis, and I picked National Academic Games. So who knows the path not taken?

But now, I still really enjoy playing guitar and singing, but I definitely do much more of a kind of a folk singer-songwriter, classic rock—Bob Dylan, Brandi Carlile type of music. So most of my angst has been exercised from me.

So, oh— from Mohammed says, I use your math videos for meditation! Well, you know, math can be a form of meditation. You know, the kind of classic form of meditation is to kind of sit still, eyes closed and focus on your breathing and become still. But, you know, anytime you're doing something mindfully and your brain isn't all over the place—that's a form of meditation.

So if you’re in a math problem and your brain is kind of still in that space, that sometimes happens in sports; it can happen when you’re listening to music, creating something, and that’s a form of meditation. So, that’s the first I’ve heard of that, but I'm happy that someone can find a Khan Academy video meditative.

So, Sanun and Abraham asks, how can we practice meditation or teach with a hyperactive four-year-old?

I don’t know. I mean, I’ve tried to convince my kids to meditate with me, and they do, you know, my older kids do a certain degree. The school they go to—the Lab Con Lab School, which I helped start—they do some meditation, which I think is really great. But for younger kids, it’s just really honestly a four- or five-year-old—even 30 seconds if they can sit silently for 30 seconds, it’s a win.

And if you build that habit, it will become a little—honestly, 10 seconds! Start with 10 seconds, and you know, give them like an M&M at the end of it, but it starts to build a muscle where you start to—you’d be surprised how many adults have trouble just sitting quietly, eyes closed with themselves, with their own mind to some degree. They want to get distracted so they don’t have to deal with everything their brain is kind of throwing at them.

So for me, you know, I found in the early—when I was starting to meditate, you know, even two, three minutes, your brain is saying, oh, someone—you know, there’s a lawnmower outside. You can’t meditate! You’re hungry! You know, your back hurts! Do I itch my nose or not? Will that break the meditation? But then you just keep doing it as a habit, and now I do 30 minutes at least once a day.

And, you know, I don’t claim to be some type of, you know, person whose mind is always still, and I've somehow reached nirvana, but there are moments where I do feel that stillness and there is—it almost feels euphoric! And, you know, when my meditation timer on my phone rings—it’ll chime—I feel like the tide. I was like, oh wow! You know, I was—I was in this inward journey! So it's—it is a muscle that you can build over time.

But, you know, my five-year-old, you know, we’re not like this family that’s like, you know, a bunch of monks, and we meditate all the time. I’m trying! I’m trying because I think, honestly, you know, there are these stereotypical things you want to instill with your kids. You want to make sure they have a lot of, you know, academic capabilities so that they get a good job. You want to make sure they’re good people, that they’re ethical, that they have a good work ethic.

But I think the resilience of meditation, uh, that you get—that’s the ultimate thing! Because life’s gonna throw curveballs at everyone, and some folks are gonna get bigger curveballs than others, but if folks can always be grounded, be present, have gratitude for what they have, and be mindful—they’re gonna get through it!

And so, yeah, I would say, keep trying! Keep trying; eventually, it’ll work!

Someone's asking me to sing. There’s no time for that! So maybe we have time for one more question. I’ve been told by the team that maybe I’ll—I still have live on social media to sing. I'll work my way up to it; I don’t have the guitar here; it’s in the garage. So, let’s see.

I'll do one. So one question—Ivana Garbaldi says, jumping on a bit late, can you talk more about Schoolhouse.world a little bit? I heard you're starting with high school math. What other subject will you be looking to roll out? Timing? Can high school students taking advanced classes volunteer tutors?

So Ivana, Schoolhouse.world is exactly that. It’s a place where students who need help in a subject can sign up for free live group tutoring sessions. And if you feel—there are high school students that are also the volunteer tutors, and actually, some of them are some of the really good tutors out there. So, you can also volunteer, and you can do both!

Right now, as I mentioned, it’s starting in high school math, but if you're at all interested in it, I would go and register, and we’re going to notify people over time because we’re—there’s no reason why we can’t expand to other subjects and other grade levels. So we’re going to be doing that probably over the next month or so; we’re going to be adding a bunch of more grade levels on.

So whether you want to be a tutor in English or the SAT, or a tutor with young kids learning math, or you want to be the recipient of the tutoring, I encourage folks to go to schoolhouse.world. Sign up! As I mentioned, we actually are looking for more students. We can easily handle several thousand more students right now, and obviously, if anyone's interested in tutoring, that’s great too because we can handle even more students.

And I’m, you know, the dream here is—this is COVID was the catalyst to make this happen—but the dream here is that in short order we have tens of thousands or hundreds of thousands of folks who are able to help each other, which obviously has the benefit where you can learn at your own time and peace on Khan Academy but you can get real live help, but in this time of social distance, hopefully, can connect people, they can build empathy for other folks.

You know, when you become a tutor, you learn the material that much better, and you’re helping folks and you’re building empathy and communication skills. So I encourage folks to check out schoolhouse.world and all the other stuff we’re doing at Khan Academy.

Just remember it’s not officially a Khan Academy project; it’s a side project. Who knows? Maybe they might converge at some point in the future.

So anyway, time always goes by fast when we’re having fun! Maybe I’ll have the guitar next to me next time, but it was really, really good questions, and thanks everyone for asking them. I think we are not doing this tomorrow, but I will see you next week at the Homeroom livestream!
