JEE Main 2027 Exam Pattern: Total Questions, Marking Scheme, Subject-Wise Distribution

JEE Main 2027 Exam Pattern at a Glance

JEE Main 2027 follows the structure refined through the 2024-2026 cycles. The paper is conducted in computer-based test (CBT) mode by the National Testing Agency (NTA), with two sessions per year — typically January and April.

This guide covers everything you need to know: total questions, marking scheme, subject distribution, time per subject, and the recent change in Section B optional question rules.

Paper 1 (B.E./B.Tech) Pattern

Parameter	Detail
Mode	Computer-Based Test (CBT)
Duration	3 hours (180 minutes)
Total Questions	75 (25 per subject)
Total Marks	300
Subjects	Physics, Chemistry, Mathematics
Question Types	MCQ (Section A) + Numerical (Section B)
Marking	+4 correct, -1 wrong (MCQ); +4 correct, -1 wrong (Numerical from 2023)
Languages	13 (English, Hindi, Assamese, Bengali, Gujarati, Kannada, Malayalam, Marathi, Odia, Punjabi, Tamil, Telugu, Urdu)

Subject-Wise Question Distribution

Each subject has 25 questions split into two sections:

Section A — Multiple Choice Questions (20 questions per subject)

• 4 options per question, only one correct
• +4 marks for correct answer
• -1 mark for wrong answer
• 0 marks if unattempted

Section B — Numerical Value Questions (5 questions per subject)

• Answer is a numerical value (integer or decimal up to 2 places)
• All 5 questions must be attempted (no optional choice from 2024)
• +4 marks for correct answer
• -1 mark for wrong answer (changed from 0 in 2023)
• 0 marks if unattempted

Important change for 2027: Until 2023, Section B had 10 questions out of which only 5 needed to be attempted (the best 5 were counted). From 2024 onward, Section B has only 5 questions and all must be attempted with negative marking. This significantly reduces the safety margin for guessing in Section B.

Total Marks Calculation

For each subject:

• Section A: 20 questions × 4 = 80 marks
• Section B: 5 questions × 4 = 20 marks
• Subject total: 100 marks

For all three subjects:

• Physics + Chemistry + Mathematics = 300 marks

Time Allocation Strategy

Most JEE Main toppers follow a 60-60-60 minute split with 5-minute review buffers. However, individual strengths vary. A practical allocation:

Subject	Suggested Time	Reasoning
Chemistry	45-50 minutes	Most questions are recall-based; faster than calculations
Physics	60-70 minutes	Numerical Section B questions are time-consuming
Mathematics	60-70 minutes	Calculus and coordinate geometry require more setup time
Buffer/Review	10-15 minutes	Re-check flagged questions and Section B answers

Start with your strongest subject to build momentum and avoid getting psychologically stuck.

Question Type Breakdown — What to Expect

Physics (25 questions)

• 4-6 Mechanics questions (Kinematics, Laws, Rotation, WEP)
• 5-7 Electromagnetism questions (Electrostatics, Current, Magnetism, EMI)
• 3-4 Modern Physics questions
• 3-4 Thermodynamics + Optics questions
• 2-3 Waves and Oscillations questions

Chemistry (25 questions)

• 8-10 Physical Chemistry questions (Equilibrium, Thermo, Electrochem)
• 8-10 Organic Chemistry questions (GOC, Mechanisms, Functional groups)
• 7-8 Inorganic Chemistry questions (p-Block, Coordination, d-Block)

Mathematics (25 questions)

• 6-8 Calculus questions (Limits, Derivatives, Integrals, AOD, DE)
• 5-7 Coordinate Geometry questions (Lines, Circles, Conics)
• 4-5 Algebra questions (Sequences, Quadratic, Binomial, Complex)
• 2-3 Vectors and 3D Geometry
• 3-4 Probability, P&C, Matrices, Trigonometry

Marking Scheme Implications for Strategy

The negative marking math:

• Skip a question: 0 marks
• Attempt and get correct: +4 marks
• Attempt and get wrong: -1 mark

Break-even logic: You need to be more than 20% confident in your answer to make attempting worthwhile. If you can eliminate to 2 options, expected value = (0.5 × 4) + (0.5 × -1) = +1.5 marks. Always attempt.

If you cannot eliminate any options, expected value = (0.25 × 4) + (0.75 × -1) = +0.25 marks. Marginal — only attempt if time permits.

Section B specifically: Numerical questions with the new -1 negative marking are the highest-risk section. Skip rather than guess unless you have confidence in your calculation.

What Has NOT Changed in 2027

• Total of 300 marks
• 3-hour duration
• 75 total questions (25 per subject)
• CBT mode through NTA
• Two sessions per year (January and April)
• Best of two scores counts for ranking

What Changed Recently (2024-2026 Cycle)

• Section B reduced from 10 optional questions to 5 mandatory questions
• Negative marking introduced in Section B (-1 for wrong)
• Biometric verification at exam centres (from 2026)
• Live photo match anti-cheat system (from 2026)
• 13-language paper option (added regional languages)

Summary Table — JEE Main 2027 Exam Pattern

Component	Detail
Mode	CBT (Computer-Based Test)
Duration	180 minutes
Total Questions	75 (25 per subject)
Total Marks	300
Section A	20 MCQ per subject (+4/-1)
Section B	5 Numerical per subject (+4/-1, all mandatory)
Languages	13
Sessions	Two (January and April 2027)

Plan your three-hour mocks around this exact structure. Replicate the time pressure, the section split, and the negative marking discipline — this is what walks into the exam hall on test day.
