JEE Main 2027 Paper 1 for B.E. and B.Tech has 75 questions carrying 300 marks. Mathematics, Physics and Chemistry each contribute 25 questions and 100 marks. The standard duration is three hours. Both multiple choice questions and numerical value questions carry negative marking, so numerical answers are not a penalty free section.
| Subject | Section A | Section B | Marks |
|---|---|---|---|
| Mathematics | 20 MCQs | 5 numerical questions | 100 |
| Physics | 20 MCQs | 5 numerical questions | 100 |
| Chemistry | 20 MCQs | 5 numerical questions | 100 |
| Total | 60 | 15 | 300 |
These details come from the official JEE Main 2027 information bulletin, checked on 9 November 2026. This guide concerns the engineering paper. Candidates applying for architecture or planning must read their own paper tables rather than use the Paper 1 total as a universal JEE Main pattern.
JEE Main 2027 exam pattern and marking scheme
Section A contains multiple choice questions. A correct answer, or the most appropriate answer, earns four marks. An incorrect answer loses one mark. An unanswered question earns zero. A question marked for review without a selected option also earns zero under the marking table. The review label should therefore not be confused with an answer.
Section B contains numerical value questions. The same basic award applies: four marks for a correct answer, minus one for an incorrect answer and zero when no numerical value has been entered. The bulletin says the answer should be rounded to the nearest integer. Candidates enter that integer using the mouse and the on screen numeric keypad in the designated answer space.
The subject table lists five numerical questions per subject. It does not describe a larger numerical question bank from which a candidate chooses five. When using practice material, match it to the 2027 table. A familiar paper format from an earlier examination year can be an unreliable guide to the number and type of questions on this paper.
How are JEE Main marks calculated?
For ordinary scored questions, multiply the number of correct answers by four and subtract the number of incorrect answers. Unanswered questions contribute nothing. As a worked example, 45 correct responses and 15 incorrect responses produce 180 minus 15, or 165 raw marks. If the other 15 questions are unanswered, they add neither marks nor penalties.
That example explains the marking arithmetic, not a predicted rank or qualifying score. NTA's bulletin separately describes converting raw subject and total scores into NTA scores and preparing merit. A raw total out of 300 is not interchangeable with a percentile. Do not read the worked example as a promised admission outcome or use it to assign yourself a rank.
There are also specific provisions for flawed questions and answer key decisions. For MCQs with more than one correct option, the bulletin awards four marks to candidates who selected any correct option. If all options are correct, the award goes to those who attempted the question. A dropped question attracts full marks for all candidates who appeared in that shift.
For a numerical question found incorrect or dropped after the challenge and verification process, the bulletin provides four marks to all candidates who appeared in that shift. Those are official adjustments. A candidate should not assume a disputed answer will receive bonus marks before NTA completes its process and publishes the applicable decision.
JEE Main Paper 1 duration and answer entry
The standard Paper 1 duration is three hours. The duration table gives four hours for PwD or PwBD candidates who are eligible for a scribe. This is a specified eligibility provision, so candidates should read the disability and examination assistance sections and their own instructions rather than assume that the additional hour applies to everyone.
For a numerical response, the final entry is what the marking scheme assesses. Check the requested quantity, the constants supplied in the question and the required integer rounding before submitting. The bulletin specifically advises calculations using the constants given in the question, if any. This matters when a practice solution uses a different approximation from the one supplied in the examination.
The paper is a Computer Based Test. Before the examination, become familiar with the answer selection and numerical entry instructions in the bulletin. A review flag is useful for returning to a question, but it is sensible to check whether an actual response has been recorded. The marking table expressly distinguishes an empty response from a correct or incorrect one.
Where to download the official 2027 pattern
Open the JEE Main official website, choose Information Bulletin and confirm that the document heading says 2027. Section 2.4 contains the examination pattern and marking tables; section 2.5 gives duration. The Documents page also lists Information Bulletin 2027 and Syllabus 2027. Keep the syllabus and pattern documents together because they answer different preparation questions.
For application decisions, see our JEE Main 2027 eligibility guide and registration and identity checks guide. Students considering a different engineering examination can also read the GATE eligibility explainer. Those admission and eligibility rules should be checked separately from the Paper 1 question and marking pattern.
