Understanding the NEET exam pattern is not optional for serious preparation. The structure of the paper determines how many questions you must attempt, which ones carry risk, and how to allocate your 200 minutes. This article lays out the complete NEET exam pattern: the Section A and Section B framework, subject-wise question distribution, marking scheme, timing, and how to think about chapter weightage across Physics, Chemistry, and Biology.

1. NEET Exam Pattern: Overview

NEET UG (Undergraduate) is a national-level medical entrance exam conducted by the National Testing Agency (NTA). It is the single qualifying exam for MBBS, BDS, BAMS, BHMS, BSMS, and other undergraduate medical and dental programmes across India.

The exam is pen-and-paper based (offline). It uses an OMR (Optical Mark Recognition) answer sheet. The question paper is in multiple languages, with English and Hindi as standard options, and several regional language options available based on the exam centre state.

2. Section A and Section B Explained

The NEET exam has been structured with a two-section format since 2021. This format applies identically to each of the four subjects.

Section Questions per Subject Attempt Rule Marks per Subject
Section A 35 All 35 compulsory 140 (35 x 4)
Section B 15 Attempt any 10 out of 15 40 (10 x 4)
Total per subject 50 Attempt 45 (35 + 10) 180

With four subjects (Physics, Chemistry, Botany, Zoology), the full paper has 200 questions, of which you must attempt 180. The maximum possible score is 720.

Important: If you mark more than 10 answers in Section B for any subject, only the first 10 responses in that section will be evaluated. The remaining responses are ignored, even if correct. Be disciplined about staying within the 10-attempt limit per subject in Section B.

3. Subject-wise Question Distribution

Subject Section A Section B (attempt 10) Total Questions Total Marks
Physics 35 15 50 180
Chemistry 35 15 50 180
Botany 35 15 50 180
Zoology 35 15 50 180
Total 140 60 (attempt 40) 200 720

4. Marking Scheme in Detail

The NEET marking scheme applies uniformly across all subjects and both sections:

  • Correct answer: +4 marks.
  • Incorrect answer: -1 mark (negative marking applies).
  • Unattempted question: 0 marks.
  • Cancelled or bonus questions: +4 marks awarded to all candidates if a question is cancelled or found to be incorrectly framed by NTA.

For a deeper analysis of how negative marking affects your score and when to skip vs. attempt, see our guide on NEET negative marking rules and strategy.

5. Exam Day Timing and Schedule

Time Activity
11:00 AM onwards Gates open for candidate entry and document verification
Until 1:30 PM Last time for candidate entry to exam hall
1:45 PM Question booklet and OMR sheet distribution begins
2:00 PM Exam begins
5:20 PM Exam ends (200 minutes from 2:00 PM)

Candidates are advised to reach the exam centre no later than 12:30 PM to complete biometric verification and document checks without rush. See our complete NEET dress code and exam day rules guide for what to carry and what is prohibited.

6. Subject Weightage and Syllabus Coverage

NEET draws questions from the Class 11 and Class 12 NCERT syllabus for each subject. NTA follows the syllabus recommended by the Medical Council of India (now National Medical Commission). The approximate split between Class 11 and Class 12 questions varies year to year but is generally close to 45:55 in Biology and similar in other subjects.

Biology carries 50% of the total marks. With Botany and Zoology together contributing 360 out of 720 marks, a strong Biology score is the primary driver of a competitive NEET rank.

7. Physics: Key Topics by Weightage

Physics is often considered the most challenging subject for NEET aspirants because of its numerical complexity. Key topics that have historically accounted for higher question frequency include:

  • Mechanics: Laws of Motion, Work, Energy and Power, Rotational Motion.
  • Electrostatics and Current Electricity.
  • Magnetic Effects of Current and Magnetism.
  • Optics: Ray and Wave Optics.
  • Modern Physics: Atoms, Nuclei, Semiconductor Devices.
  • Thermodynamics and Kinetic Theory of Gases.

Physics questions in NEET tend to be concept-based with numerical components. Pure derivation questions are rare; application of concepts to numerical problems is common. Our NEET repeater batch includes intensive Physics modules for students who underperform in Physics in their first attempt.

8. Chemistry: Key Topics by Weightage

Chemistry in NEET is split between Physical Chemistry, Organic Chemistry, and Inorganic Chemistry. Key high-frequency topics include:

  • Physical Chemistry: Mole Concept, Chemical Equilibrium, Thermodynamics, Electrochemistry, Chemical Kinetics.
  • Organic Chemistry: General Principles, Hydrocarbons, Reaction Mechanisms, Biomolecules, Polymers.
  • Inorganic Chemistry: Periodic Table and Properties, Chemical Bonding, s and p Block Elements, d and f Block Elements, Coordination Compounds.

NEET Chemistry questions tend to be more factual and definition-based in Inorganic Chemistry and more numerical in Physical Chemistry. Organic Chemistry requires understanding reaction mechanisms rather than memorisation.

9. Biology: Key Topics by Weightage

Biology (Botany and Zoology combined) is the most marks-dense section at 360 marks. Key high-frequency topics include:

  • Botany: Plant Kingdom, Reproduction in Flowering Plants, Genetics and Evolution (shared weightage with Zoology), Plant Physiology, Cell Biology and Cell Division.
  • Zoology: Human Physiology (Digestion, Respiration, Circulation, Excretion, Nervous System), Animal Kingdom, Human Reproduction, Biotechnology, Ecology and Environment, Biodiversity.

NCERT is the primary and sufficient source for NEET Biology. Questions are rarely from outside the NCERT text, diagrams, or the information boxes within NCERT chapters. Mastery of NCERT line by line is the core Biology preparation strategy.

10. How to Plan Your Section B Attempt

The Section B structure (15 questions, attempt 10) offers a strategic opportunity that Section A does not. You can skip the 5 questions you are least confident about and avoid the negative marking risk from guessing.

Practical guidance for Section B:

  • Read all 15 questions before marking any answers. Identify the 10 where you have the clearest recall or reasoning path.
  • Avoid the temptation to attempt more than 10, since only the first 10 responses are evaluated. Attempting question 11 in Section B wastes time and carries no benefit.
  • If you are confident in all 15 answers, still mark exactly 10 and leave the rest blank, unless you are running short on time and the extra 5 would only add redundancy.
  • Use the additional 5-question filter to discard questions from chapters you know you have not revised well. This protects against negative marking from unfamiliar topics.

For a complete treatment of when attempting a question is mathematically better than skipping it, see our NEET negative marking strategy guide.
