JEE Main 2027: Exam Pattern, Marking Scheme and Two-Session Strategy
JEE Main is not one exam. It is a two-session system with a percentile-based scoring model, and students who treat it as a single January paper routinely leave marks — and ranks — on the table.
Here is the structure, and then the strategy.
The paper: 75 questions, 300 marks
JEE Main Paper 1 (B.E./B.Tech) is built from three subjects — Physics, Chemistry and Mathematics — with 25 questions per subject, split into two sections:
Section A — Type: Multiple choice (MCQ) · Questions per subject: 20 · Marking: +4 correct, −1 incorrect
Section B — Type: Numerical value (NVA) · Questions per subject: 5 · Marking: +4 correct, −1 incorrect
Total: 75 questions, 300 marks, 3 hours.
Two details in that table are worth pausing on.
First: Section B is now fully compulsory. In earlier years, numerical questions carried an internal choice — ten questions of which you attempted five. Under the current pattern, all five numericals in each subject must be attempted. There is no cushion.
Second: Section B now carries negative marking. For a long stretch, numerical-value questions were penalty-free, which made wild guessing rational. That is no longer true. A blind numerical guess now costs you a mark, and the probability of hitting an exact integer by chance is effectively zero. Guess only when you have genuinely narrowed the answer.
Answers in Section B are entered with the on-screen numeric keypad and, per NTA instructions, rounded to the nearest integer. Practise that rounding rule — students lose marks by entering 4.5 when the required entry was 5, or by typing a decimal the interface will not accept.
Percentile is not percentage
This is the single most misunderstood part of JEE Main.
Your NTA score is a percentile: the proportion of candidates who scored equal to or below you. A 99 percentile does not mean you got 99% of the marks. It means roughly 1% of candidates scored above you.
Consequences that matter:
Raw marks vary by shift; percentile is normalised across shifts. With lakhs of candidates across multiple sessions and shifts, raw scores are not directly comparable, so NTA applies normalisation.
Comparing raw marks with a friend from a different shift is meaningless. Every year students spend a week anxious over this comparison. It tells you nothing.
The best of your two sessions counts. If you appear in both Session 1 and Session 2, the better NTA score is used for ranking. Session 1 cannot hurt you.
That last point is the foundation of the entire two-session strategy.
The two-session strategy
Session 1 is expected in late January and Session 2 in early April, following the pattern of recent years. Registration typically opens a few months before Session 1. These are projections based on past cycles — the official dates arrive only with the NTA notification, usually around October, at jeemain.nta.nic.in.
Given that structure, here is how to use it.
Appear in both sessions. Always.
There is no downside. The higher score counts. A student who skips Session 1 to "prepare more" is trading a free, full-scale, real-conditions attempt for a few extra weeks of study — which is a bad trade, because nothing you can do at home replicates the pressure of a real attempt.
Treat Session 1 as a real attempt, not a trial
The "I'll just see how it goes in January" mindset costs students. Attempt Session 1 as if it is the only one. Two reasons: you may score better than you expect, and a genuine attempt produces genuine diagnostic data. A half-hearted attempt produces neither.
Use the January–April gap surgically
The ten weeks between sessions are the highest-leverage period in the entire JEE calendar, because for the first time you have precise information about your own weaknesses under real conditions.
Immediately after Session 1, write down — the same evening, while it is fresh:
Which questions you got wrong and why (concept gap, calculation slip, misread, time pressure)
Which chapters ate disproportionate time
Where your paper-management broke down
Then build the ten-week plan around exactly that list. Not around "revise everything again."
Watch the board-exam collision
Class 12 board practicals and theory papers usually fall between the two sessions. Plan for it now, not in February. Realistically, you lose two to three weeks of JEE-specific study to boards. Build that loss into the plan rather than pretending it will not happen.
Eligibility: the 75% rule
There are no minimum Class 12 marks required to appear for JEE Main. But for admission to NITs, IIITs and other CFTIs through JoSAA, you must have either:
75% aggregate in Class 12 (General/OBC-NCL/EWS) or 65% (SC/ST/PwD), or
a position in the top 20 percentile of your board, in your category.
This is the rule that catches students who wrote off boards entirely. A brilliant JEE percentile with 68% in boards and no top-20-percentile qualification can cost you an NIT seat. Boards are not optional.
Verify the criteria for your specific year in the official information bulletin, as eligibility conditions have been revised in the past.
Attempts and the bigger picture
JEE Main is generally available in the year you complete Class 12 and the two following years, giving three consecutive years of eligibility. JEE Advanced is stricter — two attempts in two consecutive years, and only for candidates in the top 2,50,000 of JEE Main Paper 1. So Session 1 and Session 2 are not just about NIT admission; they are the gate to the IITs.
A subject-level note on paper strategy
Three hours, 75 questions — that is 2.4 minutes per question if you distribute time evenly. Do not distribute time evenly.
A workable default:
Chemistry first, 35–45 minutes. It is the most retrieval-based section; solving it early banks marks while you are freshest and builds momentum.
Mathematics second, 60–70 minutes. Longest solutions, most likely to consume time.
Physics third, 50–60 minutes. Conceptual, and generally the best-rewarded per minute for a prepared student.
Leave 10 minutes. For the marked-for-review pass and for entering numericals carefully.
Adapt the order to your own strength — but decide the order before the exam, not during it.
