JEE Main Exam Pattern & Marking Scheme 2027 Explained: Paper 1, 2A, 2B and Complete Question Format
The JEE Main exam pattern decides how you allocate study time, how you attempt the paper on exam day, and how a single wrong guess can cost you marks. Getting the pattern and marking scheme wrong in your head is one of the most avoidable mistakes a JEE aspirant can make. This blog breaks down the complete JEE Main 2027 exam pattern — question format, marks distribution, negative marking, exam duration, and attempt strategy — based on the current NTA pattern in effect since 2025.
JEE Main 2027 Paper 1 (B.E/B.Tech) — Complete Question Structure
Paper 1 is the most common JEE Main paper, taken by students applying for B.E/B.Tech programs at NITs, IIITs, GFTIs, and as the qualifier for JEE Advanced. Each subject is divided into two sections that test different skills.
| Subject | Section A (MCQ) | Section B (Numerical) | Total Questions | Total Marks |
|---|---|---|---|---|
| Physics | 20 | 5 | 25 | 100 |
| Chemistry | 20 | 5 | 25 | 100 |
| Mathematics | 20 | 5 | 25 | 100 |
| Total | 60 MCQs | 15 Numericals | 75 Questions | 300 Marks |
Section A — Multiple Choice Questions (MCQ)
Section A has 20 questions per subject. Each question has 4 options with exactly one correct answer. This section tests standard problem-solving across the full syllabus and is where most students spend the bulk of their preparation time.
Section B — Numerical Value Questions (NVQ)
Section B has 5 questions per subject where the answer is a number — not a multiple choice option. You type the numerical answer (integer or up to a specified decimal precision) using the on-screen keypad. Since 2025, all 5 questions per subject are compulsory — there is no longer a choice of "attempt any 5 out of 10."
JEE Main 2027 Marking Scheme — Section by Section
Understanding exactly how marks are awarded and deducted is the difference between a calculated attempt strategy and random guessing that costs you rank. Here is the complete marking breakdown.
| Section | Correct Answer | Wrong Answer | Unattempted | Partial Marking |
|---|---|---|---|---|
| Section A (MCQ) — All Subjects | +4 | -1 | 0 | None |
| Section B (Numerical) — All Subjects | +4 | See note below | 0 | None |
| Paper 2A Drawing Test | Evaluated out of 100 (2 questions, 50 each) | N/A — design/proportion based | 0 if unattempted | Yes — graded on quality |
| Every correct MCQ or numerical answer is worth 4 marks regardless of difficulty. There is no partial credit for partially correct numerical answers. | ||||
What This Means for Your Score
- Maximum possible score: 75 questions × 4 marks = 300 marks (Paper 1)
- Cost of a wrong MCQ: You lose the 4 marks you could have gained PLUS 1 mark penalty — a net swing of 5 marks compared to leaving it blank
- Unattempted questions: Always safe — zero impact on your score either way
- Guessing strategy: Blind guessing on MCQs is mathematically unfavourable — with 4 options, expected value of a random guess is negative under -1 marking
- Numerical questions: Even if no negative marking applies, an educated attempt is always better than leaving blank, since there's no downside
JEE Main 2027 Exam Duration and Ideal Time Allocation
| Candidate Type | Duration | Notes |
|---|---|---|
| General — Paper 1 (B.E/B.Tech) | 3 hours | 180 minutes for 75 questions across 3 subjects |
| General — Paper 2A (B.Arch) | 3 hours | Mathematics + Aptitude (CBT) + Drawing (pen-paper) |
| Both Paper 2A and 2B together | 3.5 hours | Extended duration for combined attempt |
| PwD Candidates (any paper) | 4 hours | Extra time as per government guidelines, scribe permitted |
Suggested Time Allocation for 3-Hour Paper 1 (180 Minutes)
This is a starting template — adjust based on your personal strength. A common and effective strategy: attempt Section A (MCQs) for all three subjects first since they are generally faster, then move to Section B (Numericals) for all three, then use remaining time for review and double-checking numerical entries.
JEE Main 2027 Paper 2A (B.Arch) and Paper 2B (B.Plan) Pattern
Students applying for Bachelor of Architecture or Bachelor of Planning programs appear for Paper 2A or 2B respectively. Both share the same Mathematics section as Paper 1 but differ significantly after that.
| Component | Paper 2A (B.Arch) | Paper 2B (B.Plan) |
|---|---|---|
| Mathematics | 25 Q (20 MCQ + 5 Numerical) — 100 marks | 25 Q (20 MCQ + 5 Numerical) — 100 marks |
| Aptitude Test | 50 MCQs — 200 marks | 50 MCQs — 200 marks |
| Drawing Test | 2 questions — 100 marks | Not applicable |
| Planning-Based Questions | Not applicable | 25 MCQs — 100 marks |
| Total Questions | 77 | 100 |
| Total Marks | 400 | 400 |
| Mode | CBT (Maths + Aptitude) + Pen-Paper (Drawing) | CBT only |
| Drawing test is evaluated subjectively based on proportion, design sense, and presentation — no negative marking applies. | ||
JEE Main 2027 Mode, Languages and Other Pattern Details
| Aspect | Detail |
|---|---|
| Exam Mode | Computer Based Test (CBT) for all sections except Paper 2A Drawing (pen and paper on A4 sheet) |
| Number of Sessions | 2 — Session 1 (January) and Session 2 (April). Best of both scores counted for final rank. |
| Shifts Per Day | Usually 2 shifts — Shift 1 (9 AM-12 PM) and Shift 2 (3 PM-6 PM), depending on number of candidates and days |
| Languages Available | 13 languages including English, Hindi, Assamese, Bengali, Gujarati, Kannada, Malayalam, Marathi, Odia, Punjabi, Tamil, Telugu, Urdu |
| On-Screen Calculator | Not provided — NTA has confirmed no virtual calculator for any session |
| Rough Work | Provided on a sheet at the exam centre — collected back after the exam |
| Question Paper Shuffling | Questions and options are shuffled per candidate to prevent copying |
| Score Normalisation | Percentile-based normalisation applied since exam spans multiple shifts and days with different difficulty levels |
JEE Main vs JEE Advanced — Pattern Comparison
| Aspect | JEE Main | JEE Advanced |
|---|---|---|
| Question Format | Fixed — MCQ + Numerical every year | Variable — changes every year, includes multi-select, matching sets |
| Total Marks | 300 (fixed) | Varies, typically 330-420 |
| Negative Marking | -1 for MCQ (Section B debated) | Varies by question type, -1 to -2 |
| Number of Papers | 1 paper (Paper 1 for B.Tech) | 2 mandatory papers |
| Difficulty Level | Procedural, pattern-based | Conceptually deeper, unpredictable format |
| Conducting Body | NTA | IIT (rotating each year) |
JEE Main 2027 Attempt Strategy Based on the Marking Scheme
Read Instructions First
Spend the first few minutes reading on-screen instructions carefully, especially confirming the exact negative marking rule for Section B that year.
Attempt Strongest Subject First
Build confidence and momentum with the subject you're most comfortable in before moving to weaker areas.
Section A Before Section B
MCQs are generally faster to attempt. Clear them first across all 3 subjects, then move to numerical questions.
Never Blind Guess MCQs
With -1 negative marking, random guessing on a 4-option MCQ has negative expected value. Only attempt if you can eliminate at least 2 options.
Attempt All Numericals
Since all 5 are compulsory and the negative marking status varies, a calculated attempt is always better than leaving blank where the downside is limited.
Mark for Review, Don't Skip
Use the "mark for review" feature for questions you're unsure about rather than leaving them completely unattempted. Return in the last 20 minutes.
Double-Check Numerical Entries
A correct calculation entered wrong (extra decimal, wrong sign) costs you the same as a wrong answer. Recheck before final submission.
Save 15-20 Minutes for Review
Use the last block of time to revisit marked questions and verify numerical answers rather than attempting fresh difficult questions.
