Exam Preparation: What the Evidence Supports

Exam preparation advice is abundant and mostly unexamined. A smaller set of practices has actual evidence.

What works

Practice testing under conditions resembling the exam, which combines retrieval practice with reduced context mismatch at recall. Spaced study across weeks rather than concentrated at the end. Interleaving topics rather than blocking them. Explaining material without notes. Working past papers to time. Sleep, since consolidation happens overnight and the night before an exam is a poor time to remove it.

What does not

Rereading notes, which is the most common strategy and among the least effective, though it produces a reliable feeling of familiarity mistaken for knowledge. Highlighting. Recopying notes neatly. Studying only the material you find difficult in isolation, since discrimination between topics is often what the exam tests. Cramming, which improves immediate performance and worsens retention, so it works only if you never need the material again.

The final week

The evidence supports consolidating rather than acquiring: practice retrieval of what you have already covered, work full past papers to time, and target the specific gaps those papers reveal. Attempting to learn substantial new material in the final days generally displaces consolidation of what you already know. Protect sleep, since a sleep-deprived exam performance loses more than the extra study hours gain. Manage arousal - moderate is useful, high impairs retrieval specifically.
