You really just taught me my entire unit in 20 min when I haven’t been able to understand it for 3 weeks in class. Thanks!

I reviewed all the PreCalculus videos (both chapter and test reviews) and was able to pass the CLEP PreCalculus exam. Thank you very much for making this information accessible AND understandable with a plethora of equations, calculations, and problems that exposed the many facets of this course of study. I'll more than likely be revisiting your page should I need any further help understanding concepts in Calculus.

I love how this video teaches more and is more to the point than an entire semester of precalculus.
