Hi, I'm Sal Khan, founder of Khan Academy, and with your support I'm excited to say: Here's just a few of the things that we've been able to accomplish together.

We now cover a wide range of academic subjects including history, science, grammar, and much more. Khan Academy is now available in more than 190 countries and translated into 18 languages.

Millions of students and teachers around the world are using Khan Academy videos, interactive exercises, and assignments. Teachers use new Khan Academy tools to assign practice exercises, identify gaps in learning, and track student progress.

Nearly 1 million students took part in our back to school challenge developing new skills and growth mindsets while celebrating their achievements.

"Are you ready to keep going and keep growing this year?"

Yeah! Research found that students who use our Official SAT Practice. We've partnered with the Advanced Placement program to provide free official practice resources for over 20 AP courses.

We're really proud of the impact we've had so far, but we're just getting started! We have big plans for 2018 and beyond.

We're going to be working on lessons across subjects for learners around the globe, and as a nonprofit, we need support from people like yourself.

So please consider becoming a monthly donor. Because together, I think we really can deliver on the mission of a free, world-class education for anyone, anywhere.
