Why flashcards work at all
Two study methods have unusually strong evidence behind them: testing yourself, and spreading your study over time. A large review of learning techniques by Dunlosky and colleagues in 2013 rated both “high utility”, while rating rereading and highlighting “low”. A flashcard is simply a convenient way to do both. The card makes you recall the answer before you see it, and a pile of cards is easy to come back to tomorrow.
That also tells you how flashcards fail: when the card can be answered without really recalling anything, or when the whole pile is done once, the night before.
1. One idea per card
If the answer has three parts, you will remember two and mark it right. Split it into three cards. A good answer is a phrase or a sentence, not a paragraph.
2. Write a question, not a heading
“Elasticity” on the front is a topic, not a question, and almost anything you say will feel like a correct answer. “What does a price elasticity of −0.5 tell you?” has one answer, and you know whether you got it.
3. Ask why and how, not only what
Definitions are the easy marks. Exams ask you to use an idea: why a rule exists, how to carry out a method, when one formula applies and another does not, what happens if a number changes. Make at least half your cards that kind.
4. Use your course’s words
Your exam will be written by your lecturer, in your lecturer’s terms and notation. A card copied from a generic deck can teach you a definition your course never used. Make cards from your own slides and lectures.
5. Say the answer before you flip
Out loud, or written down. Thinking “I know this” and flipping is recognition, not recall, and it is the main reason people feel prepared and are not. If you cannot say it, you do not know it yet.
6. Space your reviews
Review a new card the same day, then after a day, then after a few days, then a week, then longer. Each time you get it right, the gap grows; when you miss it, the card goes back to the start. This is called spaced repetition. Paper works with five boxes; apps do the scheduling for you.
7. Mix your topics
In an exam nobody tells you which chapter a question is from. Once you know a topic’s cards reasonably well, shuffle them in with the others so that choosing the method becomes part of the practice.
8. Do not make a card for everything
Cards are for things you must be able to recall cold: terms, formulas, rules, steps of a method, classic mistakes. A long argument or a worked case is better studied by explaining it from memory or by doing practice questions. A smaller deck you finish beats a huge one you abandon.
What to do with the cards you keep missing
A card you have missed five times is telling you something. Usually the card is too big, the question is vague, or you never understood the idea in the first place. Rewrite the card, or go back to the source and learn the idea properly before trying to memorise it.
Where an AI flashcard maker fits
Writing cards takes time that could go on reviewing them, which is why AI flashcard makers are popular. The risk is cards that are wrong, generic, or all definitions. If you use one, check that it works from your own course material, shows where each card came from so you can verify it, and writes questions that go beyond “what is”. Audiken’s flashcards are built that way, and export to Anki if that is where you study.
Try it with your own lectures
Audiken transcribes what is said, explains things as they come up, and builds notes, documents and study material from your own files. Accounts are opening a few at a time.
