What’s new
Version 2.0 · Updated September 9, 2026
A complete rebuild. The whole app is new: six study modes instead of three, scored practice sets with instant feedback and a summary by domain, progress that saves so you can pick up where you left off, weak-domain drills, a review deck of the questions you missed, a searchable glossary and reference section, and a larger free preview so you can complete a full practice set before deciding. Your existing purchase carries over.
