Under the latest published JEE Main Paper 1 pattern, each subject presents five numerical questions with no internal choice, and a wrong numerical answer receives the same -1 penalty as a wrong MCQ. You can still leave a question unanswered for 0 marks. This guide uses the 2026 bulletin as the baseline; confirm the 2027 bulletin when NTA publishes it.
The structure (Paper 1, B.E./B.Tech)
- 75 questions, 300 marks, 3 hours, computer-based.
- Per subject (Physics, Chemistry, Maths): 25 questions — 20 MCQs (Section A) + 5 Numericals (Section B).
- All 75 are presented with no internal choice. You may leave a question unanswered for 0; the old "attempt any 5 of 10 numericals" choice is gone.
The marking maths — and the change that catches people
- Correct: +4 (both sections)
- Incorrect: -1 (both sections, including numericals)
- Unattempted: 0
This matters because a wrong numerical costs -1 while an unanswered one receives 0. Apply attempt discipline to both sections: submit a numerical when a method or defensible estimate supports the value; skip when you have no useful basis for an entry.
Attempt policy by expected value
- MCQ, confident or two options eliminated: attempt.
- MCQ, blind guess (4 options): EV = 0.25×4 − 0.75×1 = +0.25 — marginally positive but variance-heavy; use only late, chasing a threshold.
- Numerical, confident method: attempt — JEE Main numericals take an integer answer (rounded to the nearest integer), not a GATE-style tolerance range, so carry your arithmetic to the end.
- Numerical, no method or defensible estimate: skip rather than assuming an unsupported entry is free; the -1 penalty applies.
Score scenarios
- 60 correct, 10 wrong, 5 unattempted: 230 marks.
- 55 correct, 5 wrong, 15 unattempted: 215 marks.
- 50 correct, 20 wrong, 5 unattempted: 180 marks.
These are arithmetic examples, not predicted percentiles. They show why correct, wrong and unattempted counts must be reviewed together. More attempts help only when their accuracy compensates for the penalty.
NTA score and percentile
NTA reports normalized percentile-based scores because Paper 1 is conducted across shifts with different question papers. A percentile is not the percentage of marks obtained and cannot be predicted exactly from raw marks without the relevant shift distribution. Under the latest two-session framework, the applicable best NTA score is used according to the bulletin's result rules. Confirm the 2027 session and result rules when released.
What this means for practice
Practise the published 20-MCQ + 5-numerical structure per subject and score it with +4/-1/0. Track marks, accuracy, attempts and error categories across the same mock provider; do not label a private mock score as an official percentile. Compute answer-key marks with the free JEE Main marks calculator, then keep official NTA-score expectations separate.
A mock-review template
Record subject, question type, correct/wrong/unattempted, time spent and failure category. For numericals, add unit/rounding/integer-entry mistakes. For MCQs, distinguish concept errors from low-evidence guesses. Set one behavioural rule for the next paper and verify whether it reduced repeat mistakes.
Quick answers
Are JEE Main numericals negatively marked? Under the 2026 Paper 1 bulletin, wrong Section B numerical answers lose one mark.
Can I choose only five of ten numericals? The latest pattern presents five numericals per subject with no internal choice. You may still leave a question unanswered for 0. Recheck the 2027 bulletin.
Is percentile the same as percentage marks? No. NTA score is normalized across shifts and is not raw marks divided by 300.
Can a mock predict my exact percentile? No. It can track preparation trends; official percentile depends on the examination's shift data and NTA process.
