Rereading feels productive but mostly tells you what looks familiar. Quizzes tell you what you actually know. StudyDeck builds them from your material, then keeps the weak spots in front of you until they stick.
Pulling an answer out of memory builds far stronger knowledge than rereading the page. Every StudyDeck question forces retrieval, not recognition.
Missed questions return tomorrow, then in three days, then in a week - right before you'd forget. Concepts move from 'I read that' to 'I know that' instead of slipping away.
Every question cites the passage it came from, so your quiz reflects your syllabus, not the internet's.
