Quick answer
You forget most of a chapter within weeks unless you revisit it. Revise each chapter on a spaced schedule (next day, after a week, after a month), keep one-page summaries and an error log of every mistake, and spend 20–30 minutes a day on old material. In the final month, revision is your main work.
The spaced revision schedule
| When | What to do (15–30 minutes) |
|---|---|
| Next day | Read your summary and re-solve 5 problems from yesterday’s chapter |
| After 1 week | Solve 10 mixed PYQs of the chapter without notes |
| After 1 month | A timed 20-minute set; update the summary with anything you forgot |
| Before the exam | Summary and error log only |
Three things to keep for every chapter
- A one-page summary: formulas, key results, standard methods and the traps you fell into.
- An error log: every mistake from practice and mocks with its reason and fix. Use the free tracker or a notebook.
- A short list of “must re-solve” questions that taught you something.
Subject tips
- Inorganic Chemistry: read NCERT line by line repeatedly; keep a sheet of trends and exceptions and revise it in short daily doses.
- Organic Chemistry: revise through reaction maps (conversion charts), not lists of reactions.
- Physics and Mathematics: revise by solving, not reading; a formula you cannot apply is not revised.
How do I stop forgetting what I studied for JEE?
Revisit each chapter on a spaced schedule (next day, after a week, after a month) and revise by solving questions, not just reading. Keep a one-page summary and an error log for every chapter.
How much time should I give to revision daily?
About 20–30 minutes a day during the year, rising to most of your study time in the final month.
