Waste of money

I can't even finish an entire quiz before the app closes out, no matter how fast I answer questions I have yet to be able to receive a score for any quiz. Really upset I paid for this app and it doesn't even work. Would be really helpful if it did work properly though.

Stops working!

I get about 10 questions in and the app just closes. Some of the possible answers to the questions aren't in a complete sentences. Making it hard to answer the question. Really bummed I payed almost $5 for this app.
