Great learning and review app!

I am studying for recertification and purchased the practice questions only. I’m midway through the questions. Very easy to use and mark questions for review later. One can do a written note or audio note with the question! The sync feature between laptop, desktop and smartphone (iPhone 8) are seamless. Explanations of questions are excellent with only very rare disappointments or inconsistencies. I can study in any situation with my phone handy! I highly recommend this! Great value!
