What students are saying about us

It really help a lot like helps you to understand the equations, i struggle in math so much I went from a -D to A. It also lets you view very exact/helpful solving steps.

Gerald Ingram

Great app! really the steps in solving problems are clearly explained and it helps you understand more what you are doing, after going through and reading how it does its problems and studying it i have managed to learn at my own pace and still be above grade level. I reccomend this app.
