JEE Main is held twice a year: Session 1 in January and Session 2 in April. You do not have to sit both. If you do, NTA uses the better of your two total NTA scores for your rank. This guide covers what that means for the decision and how to use the time between the two. It is based on the JEE Main 2026 information bulletin; the 2027 bulletin is awaited.
How does the best-of-two rule work?
The 2026 bulletin sets it out plainly:
- Appearing in both sessions is optional.
- If you appear in both, the better of your two total NTA scores is used for merit.
- NTA uses the better total. It does not take your best subject scores from different sessions and combine them.
- NTA merges the scores from every shift of both sessions to produce the All India Rank, which comes out after Session 2.
So a second attempt can only help your total, never hurt it. If you are unsure what an NTA score is, read how the JEE Main percentile is calculated first.
When are the two sessions?
| 2026 (completed) | 2027 | |
|---|---|---|
| Session 1 exam | 21, 22, 23, 24 and 28 January 2026 | Proposed for 22–24 and 28–30 January 2027, with 31 January as a buffer. NTA marks these dates tentative |
| Session 2 exam | 2, 4, 5, 6 and 8 April 2026 | Not yet announced |
| Session 2 applications | 1–25 February 2026, re-opened 12–13 March 2026 | Not yet announced |
In 2026, the gap between the last Session 1 paper (28 January) and the first Session 2 paper (2 April) was about nine weeks. The 2027 gap will not be known until Session 2 dates are out. Our JEE Main important dates page will carry them once NTA publishes.
Should you sit both sessions?
For most students, yes. The reasons are simple:
- Your better score counts, so the downside is limited to time, effort and the fee.
- Session 1 is the most realistic mock you will ever take. Real centre, real nerves, real paper. Whatever goes wrong there is hard information you cannot get anywhere else.
- It spreads the risk. Illness, a bad day or a technical problem in one session is not the end of your attempt.
Plenty of students do sit both. NTA’s 2026 result notice reported that 8,00,516 candidates appeared in both sessions, out of 15,38,468 unique candidates who appeared at all.
When might skipping one make sense?
There are a few honest reasons to sit only one session:
- Your Class 12 board exams or school practicals clash badly with your preparation for the second one. Check where your own board’s timetable falls in the gap.
- Your Session 1 score already meets every target you have, and the time is better spent on JEE Advanced or board preparation.
- The fee is a real burden. In 2026 the fee was charged per session: for one paper at centres in India, ₹1,000 for a General male candidate, ₹800 for a General female candidate, ₹900 for Gen-EWS/OBC-NCL male and ₹500 for SC, ST, PwD and third gender candidates. Fees for 2027 are not yet announced.
What should you do in the gap between sessions?
The gap is short. It is not enough time to learn a large part of the syllabus from scratch. It is enough time to fix the errors that cost you marks in Session 1. Here is a sensible order.
1. Write down what happened, while you still remember
Within a day or two of your Session 1 paper, write down what you can recall: which sections felt slow, which questions you skipped and why, where you changed answers, and how you used your time. Memory of the paper fades fast.
2. Sort your errors by cause
When the answer key is released, go through your responses and sort each lost mark into one of four groups:
- Careless: you knew how to do it and slipped
- Concept: you misunderstood the idea
- Time or strategy: you ran out of time, or spent too long on one question
- Didn’t know: the topic was not prepared
Our guide on how to analyse a mock test explains this method in full. It works just as well on a real paper.
3. Spend most of the gap on the biggest, most fixable group
- If careless errors dominate, the fix is process: writing units, re-reading the question, checking signs. It shows up quickly.
- If concept errors dominate, go back to the specific ideas involved, not whole chapters.
- If time was the problem, practise full papers with a deliberate plan for rounds and skipping. See JEE Main time management.
- If didn’t know dominates, pick a small number of high-value topics you can realistically cover, rather than trying to finish everything.
4. Keep taking full-length mocks, and review them properly
A few full papers that you review properly are worth more than many that you only score. Each mock should end with the same error sort.
5. Do not overreact to your Session 1 percentile
A Session 1 percentile is useful information, but it is one paper on one day. If it was disappointing, the best-of-two rule means you have a clean second chance. If it was good, the second session is a chance to make it safer.
Does Session 2 matter for JEE Advanced eligibility?
Yes. The top 2,50,000 candidates in JEE Main Paper 1 become eligible for JEE Advanced, subject to its other criteria. In 2026, NTA published the category-wise cutoffs with the final result on 20 April 2026, after Session 2. Your better total NTA score is the one that counts. See JEE Main vs JEE Advanced and the JEE Main cutoff page for the 2026 figures.
A short checklist
- Register for Session 1 when the 2027 bulletin opens, and note the Session 2 application window when it is announced.
- Treat Session 1 as a real attempt, not a trial run. Your best score counts either way.
- In the gap, review before you study. Fix the biggest fixable cause first.
- Keep practising full papers under exam conditions. Previous-year shift papers are on JEE Notes.
