Every serious JEE Main student makes mistakes. The ones who improve are the ones who keep a record of them.
What an entry looks like
Keep it short. Each entry needs only four lines:
- Question source (paper, chapter)
- What went wrong (concept, method, slip, time)
- The correct idea in one line
- A trigger that will remind you next time
Where to keep it
A notebook or a notes app works. What matters is that you can open it in 10 seconds and scan it in 10 minutes.
How to review it
- Weekly: read the week's entries and re-solve two of them.
- Before each mock: scan the last two weeks of entries.
- Before the exam: read the whole log once, chapter by chapter.
Add a pattern page
After a month, write one page of the top five repeated mistakes. Most students have a handful that cause a large share of lost marks. Seeing them together makes them easier to fix.
