Great app, has been helpful. Price however is unreasonable as most of these questions are on free websites. This app is great for giving explanations of the answers and organizing what your progress is.

This is a nice balance to studying with the NCHEC book and other resources. The questions are hard and it is definitely worth the money. Sometimes you just want to sit on the couch and study and this app allows you to do that without a bunch of notes and textbooks.

Has great study material and lots of questions.
