Chris is a Stanford-educated tutor with over 10 years experience tutoring math to students of all abilities and levels, from pre-algebra and middle school all the way through college algebra and calculus. In that time he got a lot of experience learning how to explain this stuff in a way it actually makes sense to normal people, and he brings that experience to his videos, whether you're in class now or approaching a standardized test.

"I used the ACT prep page for the week leading up to my ACT. I haven’t taken a math class in a while, so these videos definitely gave me the help that I needed. I loved that the things I needed to study were there in one page. Having them there made it so much easier to find specific topics I needed to study. These videos bumped my composite score from a 19 to a 21 in literally a week!"
"Would just like to say thanks for an awesome site. I've recently just moved to Texas from Australia to start college after leaving high school almost 8 years ago. I passed the reading and writing sections of the TSI no problem, but I was well below college level in Math. YouTube was completely useless, but your site taught me EVERYTHING I needed to know. I'm happy to say I passed the Math section of the TSI with flying colors this morning, and I'll be able to jump straight into college level courses next semester, as opposed to spending more money and more time on developmental classes. I'll be using your site throughout my college career (as long as I'm taking math)."
If you do not have an account, you should get one, because it is awesome! You can save a playlist for each test or each chapter, and save your "greatest hits" into a "watch right before the final" list (not that we recommend cramming, but when in Rome...)
