Studying for exams effectively, according to research

Rereading and highlighting feel productive but stick poorly. The two techniques best supported by cognitive science are retrieval practice (testing yourself) and spaced repetition (Dunlosky et al., 2013).

1. Test yourself instead of rereading

Retrieving an answer from memory strengthens it far more than rereading the course (Roediger and Karpicke, 2006). Turn each chapter into questions: flashcards, quizzes, explaining out loud.

2. Space out your reviews

Several short sessions spread over days then weeks beat one long night before the exam (Cepeda et al., 2006). An algorithm like FSRS works out the right moment for each idea.

3. Plan up to exam day

Start early, spread new material until a few days before the exam, then do mock exams. BrainCard builds this plan automatically from your exam date.

Frequently asked questions

How long should I study each day?

Twenty to forty minutes of active questions a day over several weeks is more effective than long rereading sessions in the final week.

What should I do the night before?

A last light review of your shakiest ideas, then sleep: sleep consolidates memory.
