1. This was the best free app I have found but there are just not enough questions with the free version.it's a great app to help me keep track of my progress.
2. Questions are challenging explanations are pretty good.Helpful questions and explanations.
3. These questions are challenging with very good explanations.
4. Wish there were more free questionsWould like more free practice questions.
5. You only get 10 questions unless you complete some incentives; like them on Facebook, post to Facebook or complete a review.
6. The questions are difficult but come with great explanations.
7. These are harder than other competing apps but I think they may be more in line with the certification exam.
8. Wish there were more without having to pay so much.Nice that it allows a question a day.
