Turn your notes, slides and lectures into flashcards and quizzes that come back right before you would forget them.
Without review, most new facts fade within days. GoodOff schedules every card with FSRS spaced repetition, so it comes back right before you would forget it.
Skip the evening of making flashcards. Bring a PDF, slides, a lecture recording or a Quizlet set. GoodOff makes the cards, a quiz and a study guide, and you can edit all of them.
