- One fact per card. Card the cell types with their one-line job description — "which cell does X?" is the exam’s favorite format.
- Rate honestly. After each card, choose Again, Hard, Good, or Easy — the spaced repetition algorithm uses your answer to decide when the card returns, right before you'd forget it.
- A few minutes daily beats marathons. Ten new cards a day is roughly 3,650 a year, retained. Deep dives: How to make flashcards that actually work · The spacing effect, explained · How to study for exams with flashcards.
