Helped me get through calculus, even though I paid for it, this app is a lifesaver. Amazing I saw the ad and didn't think it would actually work but it does you just have make it obvious on what you want it to solve, it does the work for you, all questions are correct and I love it.

Not everything, but without this, I don't think i would have a) learned as much b) passed the classes, app is a great app it gives you step by step directions on how to complete your problem and the answer to that problem.
