JEE Main 2027: A Chapter-wise Plan for the Final Stretch

With 84 days to the first JEE Main 2027 Session 1 paper, the plan that works best has three phases: finish the heavy chapters you are weakest in, then sit a full mock every week, then spend the final stretch revising your own mistakes. The chapters to start with are the ones that carry the most questions in each subject, and you can read them straight off the JEE Main chapter-wise weightage table.

84 days to Session 1: the dates to plan around

NTA's calendar lists JEE Main 2027 Session 1 for 22–24 and 28–30 January 2027, with 31 January 2027 kept as a buffer day. NTA marks these dates as tentative, so check the JEE Main and NEET exam dates page before you plan anything tightly around them. That page counts the days left in India time and is updated when NTA confirms.

Session 2 is expected in April 2027 but has not been announced. Plan for Session 1 as if it is the one that counts. If it goes well, Session 2 becomes a second chance rather than the main event.

84 days sounds like plenty until you share it between three subjects, school or coaching, sleep and the odd bad week. So this plan is as much about what to leave for later as what to do now.

Where the marks sit

JEE Main is one paper of 75 questions: 25 in Physics, 25 in Chemistry and 25 in Mathematics. Inside each subject, chapters are not worth the same. Some turn up again and again; others appear once in a while.

The table below shows the three heaviest chapters in each subject. The figures come from the same data as the full weightage page.

In short: in Physics, start with Optics, Electrostatics and Properties of Solids and Liquids. In Chemistry, start with Coordination Compounds, Organic Compounds Containing Oxygen and Redox Reactions and Electrochemistry. In Mathematics, start with Co-ordinate Geometry, Integral Calculus and Limit, Continuity and Differentiability.

These shares are long-run averages, not a forecast. A heavy chapter can be light in any one paper. But across a whole exam, time spent on a heavy chapter you are weak in pays back more often than time spent polishing a light chapter you already know well.

Phase 1: Finish your weak high-weightage chapters

Start by being honest about which of the chapters above you have not finished, or finished but cannot use under time pressure. That list is your Phase 1.

The quickest way to find out is to test yourself rather than to guess. Take a short chapter test on each heavy chapter. If you get most of it right without rushing, the chapter is in decent shape. If you get a lot wrong, or you leave a lot of questions blank, it goes on the list.

Then work through the list like this:

• Take no more than two chapters at a time, ideally from different subjects, so one hard day does not stop everything.
• Learn from your textbook and notes first. Practice questions are for checking what you know, not for learning a chapter from scratch.
• When a chapter feels done, take another chapter test. If you still miss questions on the same idea, that idea is not done yet.
• Move on when the test says so, not when the calendar says so.

Phase 1 should take roughly the first half of your time. If it is running long, drop the lightest chapter on your list rather than cutting into the mocks in Phase 2.

Do not ignore the lighter chapters completely. Some of them are short and quick to learn, and a few easy marks are still marks. They simply come after the heavy chapters you are weak in.

Phase 2: A full mock every week

Once the heaviest chapters are in reasonable shape, start sitting one full mock a week, in the same conditions as the real paper.

The real format is 75 questions for 300 marks, in 3 hours. A correct answer earns 4 marks, a wrong answer costs 1 mark, and a question you leave unanswered scores zero.

How to get the most out of each mock:

• Sit it in one go, without pausing and without your phone nearby. A mock taken in pieces tells you very little about the real paper.
• Use the same order of subjects you plan to use on the day, so the order itself becomes familiar.
• Decide your rule for guessing before the timer starts, not halfway through. A wrong answer costs less than a right one earns, so a guess where you can rule out an option or two is often worth taking. A wild guess under panic usually is not.
• Watch the clock at fixed points, for example after each subject, so you notice early if one subject is eating the others' time.

Afterwards, spend at least as long looking at the mock as you spent sitting it. The mock itself is only a measurement. What you do in the hours after it is where marks are actually gained.

A simple weekly shape works well: mock on one day, analysis the next, then the rest of the week fixing what the mock showed, usually with chapter tests on the weakest topics. If you are not sure how to do the analysis, read how to analyse a mock test and find where you lose marks.

Phase 3: Revise your own mistakes

In the final stretch before Session 1, stop starting new chapters. Anything you have not touched by now is unlikely to become reliable in time, and trying will cost you marks in chapters you already know.

Your best revision material is the list of questions you got wrong. It is made of exactly the gaps you have, which no textbook or question bank can give you.

• Go back through the wrong answers from every mock and chapter test. Redo each one without looking at the solution first.
• Sort each mistake by cause: a concept you did not understand, a formula you misremembered, a calculation slip, or running out of time. Each cause has a different fix.
• For concept gaps, reread that part of the chapter and try a few fresh questions on it.
• For slips, slow down on that kind of step, and write it out fully on paper.
• Keep sitting your weekly mock, so your timing stays sharp up to the paper.

Avoid the comfortable trap of revising only what you are already good at. It feels productive, and it adds very little.

How TestBudy fits into this plan

TestBudy's JEE Main mock follows the shape and marking of the real paper, read from the same exam profile shown on the JEE Main syllabus page. After every test you see where you lost marks by subject, then chapter, then topic, so Phase 1's list and Phase 3's mistakes come from your own results rather than from memory.

A free account includes 5 tests, which you can spend on chapter tests or full mocks. Each one gives you a score and early topic feedback.
