Good app to study in. While going through the flashcards I wrote down every concept I was unfamiliar with to study it better away from the app. Some of the flashcards were blank and didn't work, but most of them were fine.

This app really helped me prepare for my ACT exam. With it i feel ready and confident of a perfect score. I was asked by a friend to help her, and she asked how she could prepare more. So i showed her this app and she said that it was very useful 😁
