Actively recalling an answer strengthens memory more than reading the answer again. Psychologists call this the testing effect, and it holds even when the test comes with no feedback at all. Flashcards are a compact way to run hundreds of tiny tests.
The right way to review
Read the front and answer out loud or in your head before flipping. If you flip immediately, you are reading, not retrieving.
Be honest with "Again". Marking a card as known when you only half-knew it removes it from practice exactly when it needed more.
Finish the deck. A review only counts toward mastery when every card has been seen. Partial reviews leave the end of the material untouched, which is where exams love to go.
Space the reviews. Five reviews over two weeks beat five reviews in one evening.
Habits that waste time
Making cards with the answer visible in the question.
Decks that only cover the first chapter because that is where the energy was.
Reviewing in the same order every time. Shuffling prevents learning the sequence instead of the content.
What makes a good card
A good card tests one idea, has a short front and a precise back, and includes the qualifier that matters: a number, a unit, an exception. The cards Study Slay generates follow these rules and are spread evenly across the whole note, not clustered at the beginning.
