Most exam-prep apps let you mark a flashcard wrong, then do nothing with that. The card goes back in the same pile as everything else. We fixed this in Examova this year, and it’s basically one idea: a missed question needs a different review schedule than one you already know.
We run SM-2 spaced repetition across 1,746 flashcards (PMP, CIPS Level 4, Business English). A correct answer extends the interval. A missed one collapses it and brings the card back soon. Do that consistently and your review queue fills with your actual weak spots, not cards you’ve already mastered.
The harder part was grading, not the interval math. It runs server-side, not in the browser. That stops anyone reading the answer key from client-side code, and keeps the interval calculation tied to a source that can’t drift out of sync with what you actually got right.
None of this is new — practice testing and spaced review are well-tested learning techniques. The real work is making the review queue the default path, not a setting people have to find.
Full disclosure: I’m the founder of Examova (examova.com), where this runs live. Curious how others building quiz or study tools handled “what counts as mastered” — SM-2, a custom curve, or something else?
