Introduction to JEE Main 2027 Pattern

The National Testing Agency (NTA) will release the official JEE Main 2027 exam pattern (expected to remain the same as 2026) on jeemain.nta.nic.in along with the information bulletin, typically in October–November 2026. For students aiming for admission to an NIT, IIIT, or any top central-funded engineering institute, understanding the paper structure, marking style, and question types is the very first essential step.

On this page we've put together a complete breakdown of all three JEE Main 2027 papers — Paper 1 (B.E/B.Tech), Paper 2A (B.Arch), and Paper 2B (B.Plan) — in simple language, so there's no confusion when planning your preparation strategy.

One important point about JEE Main 2027: the pre-pandemic original format continues. That means the optional questions in Section B have been removed — all 5 numerical-value questions per subject are now compulsory. Negative marking applies in both sections, so accuracy matters more than ever.

For Engineering Aspirants

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

Paper 1 is the paper every JEE Main aspirant applying for B.Tech or B.E programmes takes. It is attempted on a computer and covers three subjects — Physics, Chemistry, and Mathematics — each carrying an equal weightage of 100 marks.

Subject	Section A (MCQs)	Section B (Numerical Value)	Total Questions	Total Marks
Physics	20	5 (all compulsory)	25	100
Chemistry	20	5 (all compulsory)	25	100
Mathematics	20	5 (all compulsory)	25	100
Grand Total	60	15	75	300

Key Point: All 5 NVT questions in Section B are now compulsory (no optional choice). This change came in 2024 and continues in 2027. Avoid random guessing, because NVTs also carry negative marking.

For Architecture Aspirants

Paper 2A, B.Arch Exam Pattern

Candidates interested in Architecture take Paper 2A. This paper isn't limited to Maths and Aptitude — it also has a separate Drawing Test conducted offline in pen-and-paper mode. The rest of the paper remains online.

Section	Number of Questions	Maximum Marks	Mode
Mathematics (20 MCQ + 5 NVT)	25	100	Online
Aptitude Test (MCQ)	50	200	Online
Drawing Test (Pen and Paper)	2	100	Offline
Total	77	400	Hybrid

For Planning Aspirants

Paper 2B, B.Planning Exam Pattern

Paper 2B is designed for aspirants heading toward B.Planning programmes. In place of the Drawing Test, there's a dedicated Planning section, and the entire paper is attempted on a computer.

Section	Number of Questions	Maximum Marks
Mathematics (20 MCQ + 5 NVT)	25	100
Aptitude Test (MCQ)	50	200
Planning-Based Questions (MCQ)	25	100
Total	100	400

Detailed Marking Scheme

Question-type wise marking rules and what NOT to attempt

Question Type	Correct Answer	Wrong Answer	Multiple Marked
MCQ (Section A)	+4 marks	minus 1 mark	0 marks
NVT (Section B)	+4 marks	minus 1 mark	Not applicable
Drawing (B.Arch)	Variable	No negative	Not applicable
Aptitude (B.Arch/B.Plan)	+4 marks	minus 1 mark	0 marks

Math Insight: 75 questions, +4 each for correct = max 300. To score 200+ marks (around 99+ percentile in average shift), aim for 55+ correct attempts with under 5 wrong. Every wrong answer effectively costs you 5 marks (4 lost + 1 negative), so accuracy beats volume always.

Preparation Strategy Based on Pattern

Smart Time Allocation per Section

Chemistry first (45 to 50 minutes): Highest scoring, mostly direct NCERT facts. Build early confidence and bank quick marks.
Physics second (55 to 60 minutes): Mix of formula-based and conceptual. Skip lengthy multi-concept questions on first pass.
Mathematics last (60 to 65 minutes): Most calculation-heavy section. Reserve maximum buffer time for it.
Last 10 to 15 minutes: Review marked questions, double-check NVT entries, never attempt new questions in panic mode.

Question Selection Rules

Attempt only sure-shot questions in first round (target: 50+ confident attempts).
Mark borderline questions for review, return after first pass complete.
Skip pure-guess questions, every wrong answer costs 5 marks (4 lost + 1 negative).
For NVTs: only attempt when you have arrived at a concrete numerical answer, not when you guessed the formula.

Last 90 Days Action Plan

Days 90 to 60: Complete first revision of all high-weightage chapters with 2 mocks per week.
Days 60 to 30: Second revision focused on weak chapters; 3 mocks per week with detailed analysis.
Days 30 to 7: Solve last 5 years of PYQs subject-wise; daily mini-mocks of 90 minutes.
Last 7 days: Pure revision of formulas, named reactions, key constants. No new topics.

Frequently Asked Questions

Yes, JEE Main 2027 is conducted exclusively in Computer-Based Test (CBT) mode. The only exception is the Drawing Test in Paper 2A (B.Arch), which is conducted offline in pen-and-paper format.

No. Since 2024, all 5 NVT questions per subject are compulsory. There is no choice. Negative marking of minus 1 also applies to NVTs, so random guessing is risky.

NTA uses normalisation across shifts. Formula: ((Number of candidates who scored equal or below your marks) divided by Total candidates in your shift) multiplied by 100. The best percentile from your two sessions is used for final ranking.

You select your language during application form filling. Once the paper begins you cannot switch, but the question is shown in both English and your chosen regional language simultaneously.

No. The full 3 hours can be distributed among Physics, Chemistry, and Mathematics as per your strategy. There are no sectional time locks.

Class 12 has slightly higher weightage (about 55 to 60%) in Physics and Mathematics. In Chemistry, both classes are almost equally weighted. Skipping Class 11 syllabus is not advisable as it still accounts for 40 to 50% of questions.
