ACT Prep

(from someone who can actually explain it)

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, calculus and the SAT. 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 are in class now or preparing for ACT.

ACT Prep

"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!"
