A Good Study Tool
I just passed the test yesterday and I can say that this app did help.
In "Study Mode" the app tells you where the answer to the question youre on can be found. This is a very valuable feature as it allows you to not only test your knowledge, but also directs you to the exact section you need additional study time on if youre not certain of the answer.
I noticed a few questions had the wrong answer marked as the correct one, which is the only reason I didnt give the app five stars. There is a way to submit bugs/errors right at the end of each question.
