To revise effectively for Prelims, focus on repeated cycles instead of one-time reading. Revision works when you revisit the same topics multiple times at short intervals. This strengthens retention and improves recall under exam pressure.

Use active recall while you revise. Instead of re-reading passively, close the book and test yourself — write keywords, recall facts, or solve 5–10 related questions. This helps your brain retain information longer.
Finally, link revision with mock analysis. Revise weak areas identified in tests and maintain a short mistake notebook. Consistent, focused revision — not random re-reading — is the key to avoiding forgetfulness before Prelims.
