Good but not perfect
The app got me CAPM certified in 1 month of focused practice, so kudos for that. I also liked: - the explanations and background info on each card - the sheer number of cards - statistics/performance - different ways to build quizzes But the flash card functionality is not ideal, i.e. there is no concept of spaced repetition to optimise retention. A card is either unanswered, correct, missed; plus you can flag cards. The review section is useless as it only shows you a list of answered cards with simple filters for missed and flagged. This section should be more intelligent. But, hey, it got me there 🙂
