See my other posts for the other PRINCE2 apps or select the app tag on my blog. This PRINCE2 Exam app contains a set of 100 questions, and costs 2,69 Euro.
You can start a test or use the study mode. In the study mode you get, after answering the question, tips explaining which question is the correct answer or you directly ask for the answer. You can navigate back and fort hand stop whenever you like. If you stop you get an overview with total number of answered questions, and total number of questions answered correctly. If you want you get review the incorrect questions. If you take the test you can set question and time restraints and you can bookmark specific questions for later review.
Looking at the other PRINCE2 apps, I doubt if this app will bring something new. It’s just a small database with 100 questions.
