Got an A thanks to this app

Heard from a friend that this app helped him a lot when he took chemistry. I took his advice and downloaded the app when I took gen chem. The app was very useful and I was able to learn the topics with ease. Did well on all 3 tests given in the class and eventually ended up with an A. I would recommend the app to all students who have to take chemistry.
