JEE Main 2027 Exam Pattern & Marking Scheme: The Complete Guide

If you are targeting JEE Main 2027, the first thing to get right is not a formula — it is the structure of the exam itself. Knowing exactly how many questions you face, how marks are added and deducted, and where students quietly leak marks is what separates a calm, high-scoring attempt from a rushed one. This guide breaks down the complete JEE Main 2027 paper pattern and marking scheme for Paper 1 (B.E./B.Tech).

Confirmed 28 October 2026: the pattern below is exactly what NTA’s JEE Main 2027 Information Bulletin (released 24 October 2026) prescribes. There is no change from 2026.

JEE Main 2027 exam pattern at a glance

Section-wise structure: Section A vs Section B

Each subject — Physics, Chemistry and Mathematics — is split into two sections. Together they give 25 questions worth 100 marks per subject.

Section A — Multiple Choice Questions (MCQs)

20 MCQs per subject. Each question has four options with exactly one correct answer. You click the correct option; scoring is +4 / −1.

Section B — Numerical Value Questions

5 numerical questions per subject, and all five are compulsory. There are no options — you type the numerical answer (an integer or a value rounded as instructed).

The change every aspirant must know

Section B used to be “attempt any 5 out of 10” with no negative marking. That is no longer the case. Today all 5 numericals are compulsory and they carry the same −1 penalty as MCQs. Treat numericals with the same caution as MCQs — don’t punch in a wild guess.

JEE Main 2027 marking scheme explained

The marking scheme is identical across both sections and all three subjects:

• +4 marks for every correct answer
• −1 mark for every incorrect answer
• 0 marks for any question you leave unattempted

A quick worked example

Suppose you attempt 65 of the 75 questions, get 60 right and 5 wrong (leaving 10 unattempted):

• Correct: 60 × (+4) = +240
• Wrong: 5 × (−1) = −5
• Unattempted: 10 × 0 = 0
• Net score = 240 − 5 = 235 / 300

Notice how just a handful of careless attempts eat into a strong score. This is exactly why JEE Main rewards accuracy over volume — and why the Section B change matters. Already sat a paper? Punch your correct and wrong answers into our free marks calculator to see your exact score out of 300 in seconds — then turn that into a percentile and rank estimate.

Subject-wise marks distribution

Each subject contributes equally: 25 questions and 100 marks. A common, smart way to allocate your 180 minutes is roughly 60 minutes per subject — but lean into your strongest subject first to bank marks early. (Chemistry is widely considered the fastest-scoring of the three because it is heavily NCERT-based.) For where the marks actually sit, see our guide to the high-weightage JEE Main chapters.

JEE Main Paper 2 — B.Arch (2A) & B.Planning (2B)

Most aspirants take Paper 1 (B.E./B.Tech), which is JEEnify’s focus. For completeness, Paper 2 is a separate exam for architecture and planning aspirants:

Has anything changed for JEE Main 2027?

No. NTA’s 2027 Information Bulletin (24 October 2026) keeps the structure exactly as it was: 75 questions, 300 marks, +4/−1 on both sections, a compulsory Section B, and 3 hours in two shifts (9:00 am – 12:00 noon and 3:00 pm – 6:00 pm). The paper is offered in 13 languages, and ties are still broken by the Maths NTA score first, then Physics, then Chemistry. Where the 2027 bulletin needs your attention is the paperwork around the exam: registration through MeriPehchaan, a live photograph at the time of applying, and a ₹500 late-fee window. All of it is covered in our JEE Main 2027 registration & exam dates guide.

How to practice the real JEE Main pattern (not just read about it)

Understanding the pattern is step one. Internalising it — pacing across three subjects, deciding when to skip, and resisting the −1 trap on numericals — only comes from timed practice in the real interface. That means a CBT layout with an OMR-style question palette, a live countdown, mark-for-review, and negative marking switched on, followed by a breakdown of where your marks actually went.
