JEE Main exam pattern 2027: 75 questions, 300 marks, 3 hours
The JEE Main exam pattern for Paper 1 (B.E./B.Tech) is 75 compulsory questions worth 300 marks in 3 hours, marked +4 for a correct answer and −1 for a wrong one — numericals included. JEE Main 2027 is expected to follow the pattern NTA has used since 2025.
Quick answer
- JEE Main Paper 1 has 75 questions: 25 each from Physics, Chemistry and Mathematics.
- Each subject has 20 multiple-choice questions and 5 numerical-value questions, all compulsory.
- Every question carries +4 for correct and −1 for incorrect, including numericals; unattempted questions score 0.
- The optional "attempt 5 of 10 numericals" section used from 2021 to 2024 was removed in 2025.

How does marking work in JEE Main 2027?
JEE Main 2027 is expected to award +4 marks for every correct answer and deduct 1 mark for every incorrect answer, in both the MCQ and numerical sections. A question you leave blank scores zero. The maximum is 300; because of negative marking, the minimum is −75.
That symmetry matters more than it looks. Until 2024, a wrong numerical answer cost nothing, so guessing a number was free. Since 2025 a wrong number costs a mark, exactly like a wrong option. The maths of guessing has changed: on an MCQ with four options, a pure guess is right one time in four, which averages out to about +0.25 marks — barely worth the time it takes. A guess on a numerical question is almost never right, so on average it costs you close to a full mark.
BrainStride is an AI tutor for JEE, NEET and Olympiad preparation that runs a 20-minute diagnostic, maps your weak chapters and writes a daily plan, with every solution checked by teachers. One thing it tracks is exactly this: how many marks you lose to wrong answers you could have skipped.
What does a score look like in practice?
The table below shows three students who attempted the paper differently. The student who attempted every question got five more right than the student who skipped fifteen — but finished only 10 marks ahead, because ten extra wrong answers took half of it back.
Three ways to attempt the same paper
| Student | Correct | Wrong | Left blank | Score out of 300 |
|---|---|---|---|---|
| Attempts everything | 60 | 15 | 0 | 240 − 15 = 225 |
| Skips what they can’t solve | 55 | 5 | 15 | 220 − 5 = 215 |
| Careful but slow | 50 | 10 | 15 | 200 − 10 = 190 |

What changed in the JEE Main exam pattern in 2025?
Two things changed, and both are expected to carry into 2027.
The optional numerical section was removed. From 2021 to 2024, Section B in each subject had 10 numerical questions, of which you answered any 5. Since 2025 there are exactly 5 numerical questions per subject, and all of them are compulsory. You no longer get to pick the numericals that suit you, so a weak chapter can't be dodged in Section B.
Numericals now carry negative marking. A wrong numerical answer costs 1 mark, the same as a wrong MCQ.
Did the total change?
No. The paper is still 75 answered questions, 300 marks and 3 hours. What changed is choice: every question on the screen now counts.
What does this mean for preparation?
Coverage matters more than it did. When you could skip half the numericals, a student could survive with a couple of weak chapters per subject. With 25 compulsory questions per subject, a chapter you've abandoned is marks you've abandoned. The JEE Main syllabus page lists every unit, and the syllabus tracker lets you mark what you've actually finished.
Find out which questions you should be skipping
The free diagnostic shows where your wrong answers come from — concept gaps, silly errors or time pressure.
How should you split 3 hours across 75 questions?
Three hours is 180 minutes, which works out to 2.4 minutes per question on average. In practice, questions are not equal. Many students find Chemistry quickest, Physics in the middle and Mathematics the slowest, but that is a pattern, not a rule — your own mock data is the only honest guide.
A split many toppers describe, and one we'd suggest testing in mocks:
- First pass (about 100 minutes): go through all three subjects answering only what you can solve with confidence. Don't wrestle with anything.
- Second pass (about 60 minutes): return to questions you started but didn't finish.
- Last 20 minutes: review marked answers, check numerical inputs for unit and decimal errors, and stop guessing.
Can you move between subjects during the exam?
The computer-based test lets you navigate between questions and mark them for review. Read the instructions screen in the NTA bulletin and practise on a mock in the same interface so the navigation costs you no time on the day.
How do you know your own split?
Take full-length mocks under timed conditions and look at where the minutes go, not just the score. The free Sunday mock uses the full current pattern, and past JEE Main previous year papers from 2025 and 2026 are the closest practice to the 2027 format.
How is your JEE Main score turned into a percentile?
Your raw score out of 300 is not what NTA reports. JEE Main runs in many shifts, and no two shifts get the same paper, so NTA converts raw marks into an NTA percentile score within each shift, reported to seven decimal places. Roughly, your percentile says what percentage of candidates in your shift scored at or below you. The NTA information bulletin explains the exact normalisation method.
Two consequences follow. First, a hard shift doesn't punish you: if everyone in your shift found the paper tough, the same raw marks earn a higher percentile. Second, the all-India rank is decided on the percentile, not raw marks. That's why any marks-to-percentile estimate — including ours in the JEE Main percentile calculator — should be a range, not a single number.
Does the pattern differ between Session 1 and Session 2?
No. Both sessions of JEE Main use the same Paper 1 pattern and marking scheme, and NTA uses the better of your two NTA scores. The questions differ by shift; the structure doesn't.
Four ways students lose marks to the pattern itself
None of these are about knowing the chapter.
Guessing numericals
Why it happens
Old advice from 2021–2024, when wrong numericals cost nothing, still circulates.The fix
Since 2025 a wrong numerical costs a mark. Enter a numerical answer only when you have actually worked it out.Leaving all numericals for the end
Why it happens
They feel slower, so students push them to the last twenty minutes.The fix
All 15 are compulsory and worth the same 4 marks. Attempt the ones you can solve on the first pass, like any MCQ.Rounding and units in the answer box
Why it happens
The numerical box takes a number, and students lose marks to wrong rounding or unit conversions.The fix
Read the instruction on rounding in each question and convert units before you type.Meeting the interface on exam day
Why it happens
Mark-for-review, palette colours and navigation are unfamiliar under pressure.The fix
Write at least three full mocks in a computer-based interface before Session 1.What about JEE Main Paper 2A and 2B?
JEE Main also has Paper 2A for B.Arch and Paper 2B for B.Planning. They have a different structure, including aptitude and, for B.Arch, a drawing test. Most JEE aspirants only write Paper 1, which is what this page covers. If you're applying for architecture or planning, read the Paper 2 section of the official NTA bulletin on jeemain.nta.nic.in.
JEE Main exam pattern: common questions
How many questions are there in JEE Main 2027?
JEE Main 2027 Paper 1 is expected to have 75 questions, all compulsory: 25 each in Physics, Chemistry and Mathematics. Each subject has 20 multiple-choice questions and 5 numerical-value questions. This is the pattern NTA has used since 2025; confirm it in the 2027 information bulletin when it is released.
Is there negative marking for numerical questions in JEE Main?
Yes. Since 2025, JEE Main deducts 1 mark for a wrong numerical-value answer, the same as for a wrong multiple-choice answer. A correct answer earns 4 marks and an unattempted question scores 0. Between 2021 and 2024 the numerical section had no negative marking, so older strategy advice about guessing numericals is out of date.
What is the total mark of JEE Main Paper 1?
JEE Main Paper 1 is marked out of 300: 75 questions at 4 marks each, split into 100 marks each for Physics, Chemistry and Mathematics. With negative marking of −1 per wrong answer, a raw score can technically range from −75 to 300. Your result is reported as an NTA percentile, not raw marks.
Is the JEE Main exam online or offline?
JEE Main Paper 1 is a computer-based test held at NTA exam centres across India and abroad, not a paper you take at home. It runs in multiple shifts over several days in each session, and NTA normalises scores across shifts into percentiles so that a harder shift does not disadvantage its candidates.
Is JEE Main 2027 pattern going to change?
NTA had not announced any change for JEE Main 2027 as of September 2026, and the 2027 bulletin was not yet out. The safest assumption is the 2025–2026 pattern: 75 compulsory questions, 300 marks, 3 hours, +4/−1 for all questions. Check jeemain.nta.nic.in when registration opens, expected around late October to November 2026.
How much time should I spend per question in JEE Main?
JEE Main gives 180 minutes for 75 questions, about 2.4 minutes each on average. Most students do better with two passes: answer everything they are confident about first, then return to partially solved questions. Your real split should come from timed mocks, because the time each subject takes differs from student to student.
