Not well thought out
I found this app to be difficult to use and not worth the money that I paid for it. Each time you press the quiz button there are different number of questions. Regardless of how many questions there are it doesn't give you enough time to finish the quiz. There's no immediate feedback on the questions. There is a review but it has bugs. Often the review won't go over all the questions you answered
