Your 100-day JEE Main plan, chapter by chapter

A hundred days sounds like a lot until you list the chapters. Most students reach the last three months with half of them still shaky. This plan works if you follow it roughly, not perfectly.

Start with what carries the most marks

Not every chapter is worth the same. A handful of high-weightage chapters make up a large share of the maths paper, so they come first.

The plan in four phases

1. Day 1–35Finish the high-weightage chaptersOne chapter every 6–7 days. Watch the parts, solve the practice set the same day and do the PYQs on the weekend.
2. Day 36–65Cover the rest, lightlySmaller chapters take 2–3 days each. Aim for the PYQs, not every textbook exercise.
3. Day 66–85Mocks and fixing gapsTwo full mocks a week. Spend as long reviewing a mock as you spent writing it.
4. Day 86–100Revise, don't learnOnly formula sheets, notes and your own mistake log. No new chapters in the last two weeks.

What a normal day looks like

• 40 minutes of video, one part at a time, before school or right after.
• 30 minutes on that part's practice set the same evening, while it's fresh.
• 20 minutes on yesterday's mistakes, written into a single notebook.
• Sundays for PYQs and one timed section test.

When to start mock tests

Start full mocks in phase 3, not before. After each mock, sort every wrong answer into one of three buckets: didn't know the concept, knew it but made a slip, or ran out of time.

If you're already behind

Cut phase 2 short. Pick the high-weightage chapters you haven't done, skip the rest for now and protect the last two weeks for revision.
