Title: It's a Must Have!
Review: I was freaking out over the fact that I only had 5 weeks until my junior year when I would be taking AP Calculus. I found this product and figured "Why not...it cant hurt?" Little did I know that it would be the most helpful thing I've ever bought. Using it for a few hours a week helped me get through the class easier than I could have ever expected...BUY IT.
