Spaced Repetition for Maths and Science: What Actually Works

Spaced repetition is the most studied technique in learning science. It works — but students often misuse it in Maths and Science, where recognising a fact isn't the same as being able to solve a question.

What flashcards are for

• Definitions, laws, formulae and standard results.
• Vocabulary in Biology and Chemistry.
• Non-formula-book identities and integrals in Maths.

What flashcards are not for

You can't flashcard your way to solving quadratic simultaneous equations or a mechanics problem. For skills, the equivalent of spacing is returning to the question type at increasing intervals.

Space your past-paper practice too

Revisit a topic three days later, then a week, then a fortnight. Each pass uses fresh questions on the same topic — not the same paper twice.

Combine cards, questions and mistake logs

The strongest routine layers three habits: daily flashcards for facts, spaced problem practice for skills, and a mistake log for the specific gaps that keep resurfacing.
