How JEE Main Negative Marking Works
Verified: NTA JEE Main Information BulletinNegative marking is designed to eliminate random guessing and measure conceptual accuracy. In JEE Main, every incorrect bubble deducts marks from your hard-earned positive score. Below is the official marking structure verified against the latest examination bulletin.
| Question Type | Correct Marks | Negative Penalty | Rule / Exception |
|---|---|---|---|
| Section A (Multiple Choice Questions) | +4 | -1 (25%) | Standard 4-option single-choice questions. |
| Section B (Numerical Value Type) | +4 | -1 (25%) | Numerical response questions evaluated as per latest NTA CBT pattern. |
| Unattempted / Left Questions | 0 | 0 | No penalty for unattempted questions. |
How to Calculate Your JEE Main Score
Use the formula below to manually verify your raw score or enter your responses into our interactive calculator above for instant evaluation.
Formula: (48 × 4) - (12 × 1) = 192 - 12 = 180 Marks out of 300. A score of 180 typically yields an estimated 98.5 to 99.1 NTA percentile, securing top NIT CSE/ECE seats.
Negative Marking Rules for JEE Main 2026-27
- •NTA JEE Main Paper 1 Pattern: 75 questions to be attempted out of 90 total questions (25 each in Physics, Chemistry, and Mathematics).
- •Section A (20 MCQs per subject): +4 for correct option, -1 for incorrect option.
- •Section B (5 out of 10 Numerical per subject): Candidates attempt any 5 questions per subject. Negative marking of -1 applies to incorrect numerical inputs.
- •Rounding Off: Answers in Section B must be entered as exact integers or rounded decimals strictly according to the CBT prompt.
Tips to Avoid Losing Marks in JEE Main
- Strategy Tip #1
Select the 5 Easiest Section B Numericals: Since you have 10 choices per subject, filter for straightforward single-step numericals to prevent -1 deductions.
- Strategy Tip #2
The 20% Break-Even Rule: With +4/-1, random guessing gives 0 expected value. Only guess if you can eliminate at least 2 incorrect options.
- Strategy Tip #3
Accuracy over Attempt Volume: A student attempting 50 questions with 90% accuracy scores 175 marks, outscoring a student attempting 70 questions with 60% accuracy (140 marks).
- Strategy Tip #4
Physics & Chem Speed Buffer: Build time reserve in Chemistry to dedicate extra time to tricky Math numerical steps.

Frequently Asked Questions About JEE Main
Is there negative marking in Section B numerical questions in JEE Main?▼
Yes. As per recent NTA guidelines, both Section A (MCQs) and Section B (Numerical Value Questions) carry -1 negative marking for every incorrect answer.
How is the break-even accuracy calculated for JEE Main?▼
For +4/-1 questions, break-even accuracy is 1 / (4 + 1) = 20%. Any accuracy above 20% on educated guesses yields a positive net return.
What is a safe score in JEE Main for top NITs?▼
A score of 180+ out of 300 generally secures a 99+ percentile, guaranteeing CSE/ECE branches in top National Institutes of Technology (NITs).
