The direct answer
The JEE Main Paper Structure
| Parameter | JEE Main (2026) |
|---|---|
| Total questions | 90 (30 per subject) |
| Per subject split | 20 MCQ + 10 Integer-type |
| Total time | 180 minutes (3 hours) |
| MCQ marking | +4 correct, -1 wrong, 0 unattempted |
| Integer marking | +4 correct, 0 wrong, 0 unattempted |
| Avg time per question | 2 minutes |
The key insight: Integer questions have ZERO negative marking. Every blank integer is a free chance at +4 marks. MCQs reward accuracy but punish wrong guesses — only guess when you can eliminate 2+ options.
Your exam day preparation checklist — leave nothing to chance
Phase 1: First Pass (0–90 Minutes)
Goal: Attempt every question you can solve in under 3 minutes. Skip everything else — mark it for review. By the end of Phase 1, you should have 55–65 questions answered.
Recommended subject order:
Chemistry (Start Here)
Inorganic first (fact-based, fast to answer or skip) → Organic next (mechanism-based, medium speed) → Physical last (calculation-heavy, needs more time).
Chemistry gives you the quickest marks. Build momentum here.
Mathematics
Shortcut questions first (Quadratic, Binomial, simple Calculus) → Skip anything requiring more than 3 minutes of setup.
Math is the time sink. Don't let one question eat 10 minutes.
Physics
Formula-application questions first → Skip long derivation setups.
Same 3-minute rule. If you don't see the path in 3 minutes, skip.
What to DO on first pass for EACH question:
- Read the question (30–45 seconds).
- Decision: Can I solve this in under 3 minutes?
- YES → Solve, mark answer, move on.
- PROBABLY → Mark for review (MCQ: mark your best guess, flag it). Integer: flag it.
- NO → Skip entirely, flag for later.
| Time Checkpoint | Target | If Behind |
|---|---|---|
| 30 min | 15-20 questions | Speed up, skip borderline questions |
| 60 min | 35-40 questions | Focus on easy marks, reduce thinking time |
| 90 min | 55-65 questions | Good pace — continue to Phase 2 |
Phase 2: Second Pass + Integer Questions (90–150 Minutes)
Part A: Return to flagged MCQs
You now know your overall progress. Judge time allocation better. Attempt flagged questions: 3–4 minutes each maximum. If still unclear after 3 minutes: lock your best guess, move on.
Part B: Integer questions (no negative marking)
Critical rule: Attempt EVERY integer question. Even if you have no idea — write something. Wrong integer = 0 marks, not -1. There is zero downside to attempting.
Strategy for uncertain integer answers:
- Try to eliminate obviously wrong magnitudes (if the answer should be between 0 and 100, don't write 999).
- Use dimensional analysis to check your answer's units.
- If totally lost: write "2" or "0" — these are common answers in physics numericals.
Phase 3: Review + Strategic Guessing (150–180 Minutes)
30 minutes left. This phase can be worth 20–40 marks if used correctly.
Review attempted questions
- Go through answers you marked with uncertainty.
- Look for: calculation errors, misread questions, wrong units.
- Don't change correct answers out of panic. Only change when you spot a clear error.
Strategic guessing (MCQ only)
You have unattempted MCQs. For each, spend 45–60 seconds trying to eliminate 2 wrong options.
| Elimination | Probability | Expected Value | Verdict |
|---|---|---|---|
| Eliminate 2 options | 50% | +4×0.5 + (-1)×0.5 = +1.5 | GUESS |
| Eliminate 1 option | 33% | +4×0.33 + (-1)×0.67 = +0.66 | Marginal |
| Eliminate 0 (pure guess) | 25% | +4×0.25 + (-1)×0.75 = +0.25 | Skip unless desperate |
When you can eliminate 2 options: expected value is +1.5 marks per guess. This is positive expected value. Guess aggressively.
When you eliminate nothing: expected value is only +0.25. Only guess if you're desperate for the percentile.
Phase-wise time allocation for maximum score in 180 minutes
5 Exam Day Mistakes That Cost 20–40 Marks
Mistake 1: Spending 8–10 min on ONE hard question
You feel like giving up is losing. You're actually losing time for 5 easier questions. The 3-minute rule is absolute. Set a mental timer.
Mistake 2: Attempting in serial order (Q1, Q2, Q3...)
Q1 might be the hardest question on the paper. Q47 might be easiest. Skim ALL 30 questions in a subject in 5 minutes. THEN start with the easiest.
Mistake 3: Skipping integer questions
No negative marking. Every blank integer is a free chance at +4. Even systematic guessing on integers beats not attempting.
Mistake 4: Poor time tracking
At 60 min: 30-35 questions done. At 90 min: 55-60 questions done. At 120 min: All first-pass attempts complete. If behind: speed up.
Mistake 5: Changing correct answers in Phase 3
Research shows: first instinct is more often correct. Only change if you identify a specific, clear error. Never change because "it seems different now."
Bonus: Forgetting the 3-minute rule under pressure
In the last hour, panic sets in. Remember: if you can't solve it in 3 minutes, skip. Don't gamble hours on unsolvable questions.
What to Do the Night Before
| Time | Do This | Why |
|---|---|---|
| 9:00 PM | Stop all studying. Review formula sheets (30 min). | New material causes anxiety. Review only consolidates. |
| 10:00 PM | Prepare exam kit: admit card, ID, stationery, water, dark chocolate. | Morning rush causes forgotten items. Prep now. |
| 10:30 PM | Light reading (NOT JEE material). | Blue light and intense reading disrupt sleep onset. |
| 11:00 PM | Sleep. Non-negotiable. 7 hours minimum. | Sleep consolidates memory. Last-minute cramming is counterproductive. |
Note: Reading new chapters or attempting new problems the night before is counterproductive. Your brain consolidates memory during sleep, not during last-minute cramming. Sleep is active preparation.

Exam Morning Routine
- Wake up 2.5 hours before exam start time. No exceptions.
- Breakfast: Something you've eaten before. NO new foods on exam day — they can cause digestive upset.
- Travel: Leave 45 minutes earlier than necessary. Traffic is unpredictable.
- Arrival: Be at the centre 30 minutes before entry.
- Mental state at the gate: Take 5 slow breaths. The exam shows what you already know — not learning something new. You are ready.
Frequently Asked Questions
Which subject should I start with in JEE Main?
Chemistry first. It is the fastest and most scorable subject. Start with Inorganic (fact-based, quick to answer), then Organic (mechanism-based), then Physical (calculation-heavy, use remaining time). Build early momentum and confidence.
How many questions should I attempt in JEE Main for 95+ percentile?
Target 75-82 questions with 85%+ accuracy. Going beyond 82 with declining accuracy backfires due to negative marking. It's better to attempt 78 with 90% accuracy than 90 with 75% accuracy.
When should I skip a question in JEE Main?
Skip any question you cannot solve in 3 minutes during the first pass. Mark it for review. Do not spend more than 3 minutes on any single question during Phase 1 — this is an absolute rule.
How do I use the last 30 minutes of JEE Main?
Use the last 30 minutes for review and strategic guessing. Check calculations on attempted questions. Re-read flagged questions. Then attempt every remaining MCQ using educated elimination — guess when you can eliminate 2+ wrong options. Never leave an MCQ blank if you can eliminate 2 options.
Should I attempt all integer questions in JEE Main?
Yes, attempt EVERY integer question. There is zero negative marking for integer-type questions. Even a guess has positive expected value compared to leaving it blank. Write something for every integer answer — even "0" or "1" can be correct.
Which subject should I start with in JEE Main?
Start with Chemistry for most students - it is typically the fastest to answer. Begin with Inorganic (fact-based), then Organic, then Physical. Move to Maths and Physics after.
How many questions should I attempt in JEE Main for 95 percentile?
Attempting 65-75 questions with 85%+ accuracy typically yields 95+ percentile. Focus on accuracy over quantity. A single wrong MCQ costs 5 marks net.
Should I use the calculator in JEE Main?
The on-screen calculator is slow. Use it only for complex calculations (like large numbers in Physics). For simple arithmetic, do it mentally or on the rough sheet.
Frequently Asked Questions
What if I finish early in JEE Main?
Do not leave early. Use the remaining time to review calculations and check for silly mistakes. Many students lose 10-15 marks in the last 20 minutes by rushing. Stay until the end.
Should I bring a watch to JEE Main?
No. The exam computer has a timer. Your seat will have a clock. Bring only the admit card, photo ID, and stationery. Extra items cause anxiety.
How do I handle a question I cannot solve at all?
Mark it, guess strategically (if MCQ), and move on. Do not spend more than 3 minutes on any question in the first pass. The hardest question is not worth as much as 3 easy questions you miss by spending too much time.
