Passed the test
I had a book to study with also but I mostly used the app. It's questions then answer explanations. If you look at the explanations to the ones you missed it helps a lot. It's not perfect, but it helped me.
App not worth it
This app is not worth $4.99. There are so many questions with misinformation; there are incomplete questions and incomplete explanations of answers. I also found grammatical and spelling errors. Quite honestly, this app needs a lot of work and I should get a refund.
Convenient
This app is helpful and convenient. I can study more often since it is on an app. When you understand a concept in 'Study Mode', you check it off. I could not find anything helpful online and found this worth the $4.
