How to make flashcards that actually work

1. One idea per card. Split big topics into several cards.
2. Ask a question. "Mitochondria" on the front is weak; "Where does aerobic respiration happen?" is strong.
3. Keep answers short, ideally a few words or one line.
4. Make both directions for vocabulary and definitions.
5. Add a picture where it helps (see dual coding).
6. Write them yourself in your own words.

• Answer before flipping, out loud or written.
• Keep one big shuffled stack rather than many small ones. In a flashcard study, spacing cards out within a large stack beat cramming small stacks for 90% of students (Kornell, 2009).
• Use boxes: the Leitner system moves known cards to less frequent review.
• Don't drop cards too soon. Getting a card right once doesn't mean you'll remember it next week.

Both work. Paper is quick for diagrams and doesn't come with notifications. Digital is easier to edit, shuffle and carry, and can schedule reviews for you. Our free flashcard maker turns a pasted list ("term - definition") into a deck, sorts cards into Leitner boxes and saves them in your browser, with no sign-up.

• Cards with paragraphs on the back.
• Only reading the cards, not testing.
• Making beautiful cards and never reviewing them.
• Using flashcards for everything. They're great for facts; for maths methods and essays, you also need practice questions.

Flashcards suit the facts you need instantly: formulas, units, definitions, chemical tests, angle rules. Some examples:

• Front: Formula for the area of a circle? Back: $\pi r^2$
• Front: Unit of electrical resistance? Back: ohm (Ω)
• Front: What is a catalyst? Back: A substance that speeds up a reaction without being used up.

For methods, put a short question on the front and work it out on paper before checking: "Factorise $x^2 + 5x + 6$" with $(x + 2)(x + 3)$ on the back.
