Very Helpful!

Great app for study or review. Search for a specific topic, or or study and review using questions in list form. Plenty of questions and answers on every topic.

Good Questions, UI Needs Work

I like this app, the questions are useful. The UI is not very user friendly and could use some effort. Try breaking questions into sections that can be completed, and let the user give an indication of which ones have been answered. Allow them to indicate (in red?) which ones they got wrong. Also, having a random question test mode where the app picks a user specified number of questions for them to answer. Good questions!
