The NEET negative marking rule is one of the most misunderstood aspects of the exam. Many students either attempt every question recklessly and lose hundreds of marks, or become so fearful that they skip questions they would have answered correctly. Neither extreme helps. Understanding how the marking scheme works, and building a disciplined attempt strategy, is one of the highest-leverage skills you can develop before exam day.
At Suresh Dani’s Classes, we have guided thousands of NEET aspirants through this exact challenge. This guide breaks down the marking rules, the maths behind risk decisions, and the subject-specific tactics that toppers use to maximise their final score. Whether you are appearing for the first time or as a NEET repeater, these principles apply equally.
1. What Is NEET Negative Marking?
Negative marking means that choosing a wrong answer reduces your total score. In NEET, the National Eligibility cum Entrance Test for undergraduate medical admissions, every incorrect response subtracts one mark from your running total. The system was designed to discourage blind guessing and to reward genuine subject knowledge over probabilistic attempts.
NEET is conducted by the National Testing Agency (NTA) under the guidelines of the National Medical Commission. The negative marking policy has remained consistent across the current exam format: +4 for correct, -1 for wrong, 0 for unattempted. This applies to all 180 questions spread across Physics, Chemistry, and Biology.
Key fact: A student who answers 150 questions correctly and 30 incorrectly scores 150 x 4 – 30 x 1 = 600 – 30 = 570 marks. A student who answers 140 correctly and 0 incorrectly scores 140 x 4 = 560 marks. Attempting carefully with good accuracy beats selective skipping.
2. NEET Marking Scheme Explained
The full NEET paper carries 720 marks. Here is how the marks distribute across subjects:
| Subject | Total Questions | Questions to Attempt | Max Marks |
|---|---|---|---|
| Physics | 50 (35 in A + 15 in B) | 45 (35 + 10 from B) | 180 |
| Chemistry | 50 (35 in A + 15 in B) | 45 (35 + 10 from B) | 180 |
| Biology (Botany) | 50 (35 in A + 15 in B) | 45 (35 + 10 from B) | 180 |
| Biology (Zoology) | 50 (35 in A + 15 in B) | 45 (35 + 10 from B) | 180 |
| Total | 200 | 180 | 720 |
The marking rule for each attempted question is: correct answer = +4, wrong answer = -1, unattempted = 0. There is no partial marking or bonus for speed. Every question carries equal weight of 4 marks.
3. Section A and Section B: Does Negative Marking Differ?
From 2021 onward, NTA restructured NEET into two sections per subject. Section A has 35 compulsory questions. Section B has 15 questions, of which students must attempt any 10. The negative marking rule does not change between sections.
If you attempt more than 10 questions in Section B, the system evaluates only the first 10 responses. If even one of those first 10 is wrong, the -1 deduction applies. Many students mistakenly believe Section B is “optional marks only” with no downside. That is incorrect. Choosing which 10 questions to answer in Section B is itself a strategic decision where negative marking must guide you.
In Section B, read all 15 questions before marking any. Identify the 10 you are most confident about and mark only those. This two-pass approach can add several marks to your final score.
4. The Mathematics of Negative Marking
Understanding the expected value calculation helps you decide rationally when to attempt a question. For a standard 4-option MCQ where you have no idea of the answer, the probability of guessing correctly is 25 percent and of guessing incorrectly is 75 percent.
Expected value = (0.25 x 4) + (0.75 x -1) = 1.0 – 0.75 = +0.25. Mathematically, pure random guessing on 4-option questions actually has a slightly positive expected value. However, this assumes perfectly random choices. In practice, students often select options they are partially biased toward, making their “random” guesses worse than true random.
The situation improves dramatically when you can eliminate options. If you eliminate one wrong option, your probability of guessing correctly jumps to 1 in 3, giving expected value = (0.33 x 4) + (0.67 x -1) = 1.32 – 0.67 = +0.65. Eliminate two options and the expected value = (0.5 x 4) + (0.5 x -1) = 2.0 – 0.5 = +1.5. Always attempt when you can narrow down to two options.
5. Risk Strategy: When to Attempt and When to Skip
Struggling with NEET Strategy? Get Expert Guidance
Our faculty at Suresh Dani’s Classes have helped 1000s of students crack NEET with structured coaching and personalised mock test reviews.
Explore NEET CoachingThe decision tree for any uncertain question in NEET should follow this logic:
- Confident (above 85 percent certainty): Always attempt. Expected value is strongly positive.
- Can eliminate 2 options (50 percent chance): Attempt. Expected value is +1.5 marks.
- Can eliminate 1 option (33 percent chance): Attempt with caution. Expected value is +0.65 marks, but this assumes your guess among remaining options is random.
- No idea at all (25 percent chance): Skip or mark for review. Tiny positive EV does not justify the risk of habitual guessing.
- Trap question you recognise: Skip. Recognising a trap does not mean you will avoid it under time pressure.
A practical rule used by many toppers: if you cannot explain in one sentence why the correct option is correct, do not mark it. Vague familiarity is not the same as knowledge.
6. Subject-Wise Approach to Negative Marking
Physics
Physics tends to be where students lose the most marks to negative marking. Numerical problems feel solvable but carry hidden traps in unit conversion, significant figures, and formula misapplication. Rule: do not attempt a Physics numerical unless you have worked out the calculation fully. Skipping a Physics question is far better than making a calculation error on the final step.
Chemistry
Organic Chemistry reactions and Physical Chemistry calculations are the two risky zones. Inorganic Chemistry is relatively safer for confident attempts since it is largely factual. Organic reaction mechanisms with multiple steps are best skipped unless you are fully certain of every intermediate.
Biology
Biology (Botany and Zoology combined) is where most students attempt the most questions and also where the most marks are available. Because Biology is largely factual, students often feel confident and over-attempt. Watch out for “except” questions, definitional traps, and classification questions where two options seem correct. Read the question stem carefully before selecting.
7. Common Mistakes Students Make with Negative Marking
- Marking the first option that seems familiar: Familiarity without certainty is the top cause of avoidable negative marks.
- Not using the review/marking feature: Flag uncertain questions in the first pass, then revisit with fresh eyes in the second pass.
- Changing correct answers: Research consistently shows that first instincts are correct more often. Changing an answer should require a specific new reason, not just anxiety.
- Ignoring time pressure: Rushing in the final 10 minutes leads to reckless guessing and significant negative marking.
- Treating all subjects equally: Your personal accuracy in Physics vs Biology vs Chemistry will differ. Track your subject-wise accuracy in mock tests and apply different thresholds accordingly.
8. Using Mock Tests to Calibrate Your Attempt Strategy
The only way to know your personal accuracy threshold is to measure it rigorously across practice tests. After every mock test, calculate: total questions attempted, total correct, total wrong, and your accuracy percentage per subject. Build a personal decision rule based on this data, not on general advice.
If your Physics accuracy in mock tests is 58 percent, then eliminating one option (bringing your expected accuracy to around 67 percent) is the minimum before attempting Physics questions you are unsure about. If your Biology accuracy is 82 percent, you can attempt more aggressively.
Track this in every mock test: Accuracy Rate = (Correct Attempts / Total Attempts) x 100. A student targeting 600 marks should aim for accuracy above 75 percent across all subjects combined.
9. Attempt Planning: Setting Realistic Targets
Score targets determine attempt targets. Here is a planning framework commonly used by our faculty at Suresh Dani’s Classes:
| Target Score | Questions to Attempt | Required Accuracy | Approx Rank (General) |
|---|---|---|---|
| 650+ | 170+ | 92%+ | Top 1,000 |
| 600-650 | 160-170 | 85-90% | 1,000-5,000 |
| 550-600 | 150-160 | 80-85% | 5,000-15,000 |
| 500-550 | 140-150 | 75-80% | 15,000-35,000 |
| 450 (qualifying) | 130-140 | 70%+ | 35,000-80,000 |
These targets assume near-perfect negative marking management. A student attempting 170 questions with 75 percent accuracy scores 170 x 0.75 x 4 – 170 x 0.25 x 1 = 510 – 42.5 = approximately 467 marks — well below their attempt potential. Accuracy, not volume of attempts, is the primary lever.

12. Frequently Asked Questions
How many marks are deducted for a wrong answer in NEET?
One mark is deducted for every incorrect answer in NEET. Each correct answer earns 4 marks, so a wrong response changes your net by minus 5 marks relative to a correct one.
Is there negative marking in NEET for unattempted questions?
No. Unattempted or skipped questions carry zero marks. There is no penalty for leaving a question blank in NEET.
What is the total marks in NEET 2025?
NEET 2025 has 180 questions carrying 720 total marks (4 marks each). With negative marking, the minimum possible score is minus 180 if all 180 questions are answered incorrectly.
Should I attempt questions I am not sure about in NEET?
Attempt if you can eliminate at least two options, giving you a 50 percent or better chance. With 4 marks for correct and 1 mark deducted for wrong, the expected value becomes positive when you have eliminated two distractors.
Which subjects have negative marking in NEET?
All three subjects in NEET carry the same negative marking rule: Physics, Chemistry, and Biology (Botany and Zoology). The penalty of minus 1 applies equally across all sections.
Does negative marking apply to Section B optional questions in NEET?
Yes. The negative marking rule applies to both Section A and Section B. In Section B you attempt 10 out of 15 questions, but any wrong answer among those 10 still attracts a minus 1 deduction.
What is the break-even attempt accuracy to avoid losing marks in NEET?
At random guessing (25 percent accuracy on 4-option MCQs), expected score is zero. You need above 20 percent accuracy just to stay at zero when guessing. Targeting 70 percent or higher accuracy before attempting a question is advisable.
Can negative marks reduce my NEET score below zero?
Yes, technically possible. If a student answers all 180 questions incorrectly the score would be minus 180. In practice, even with poor performance the score rarely goes deeply negative because students skip uncertain questions.
