NEET UG 2026 exam pattern: 180 questions, +4/−1 scoring, 720 marks

A 3-hour 20-minute NTA pen-and-paper (OMR) test across Physics, Chemistry, Botany and Zoology. Here's the official format, section split, and scoring rules.

NEET UG (National Eligibility cum Entrance Test, Undergraduate) is a 3-hour 20-minute pen-and-paper test conducted by the National Testing Agency on a single day each year. Each candidate attempts 180 questions - 45 each in Physics, Chemistry, Botany, and Zoology. Scoring is +4 for correct, −1 for incorrect - blind guessing has a real cost. Maximum score: 720 marks.

How are the 180 questions split across subjects?

Botany + Zoology together form the Biology section (90 questions / 360 marks). For NEET UG candidates this is by far the heaviest subject and the highest-yield area to master. Every question is single-best-answer MCQ. NTA dropped the older Section A / Section B split in 2024 - all 180 questions are now compulsory.

Scoring rules: +4 / −1 explained

The −1 penalty makes pure guessing negative-EV: random 4-option answering averages about −0.25 marks per question. Skip if you genuinely don't know. Educated-guess only after eliminating at least one option. And double-check your OMR fill-in - a stray mark in a neighbouring bubble can void an otherwise correct answer.

Worked example

If you attempt 160 of 180 questions and get 145 correct, 15 wrong: 145 × 4 − 15 × 1 = 580 − 15 = 565 / 720. Skipping 20 doesn't hurt; the 15 wrongs cost you 15 marks vs. just leaving them blank. A 565 raw score historically maps to a comfortable MBBS seat at a government medical college for General-category candidates.

How should you split time across the 180 questions?

You have ~67 seconds per question on average (200 minutes ÷ 180). A workable split for most aspirants:

• Biology - Botany + Zoology (90 qs): ~55 min - fastest section; recall-heavy, NCERT-driven. Aim for one pass with high confidence
• Chemistry (45 qs): ~50 min - inorganic / organic / physical mix; named reactions and exceptions decide accuracy
• Physics (45 qs): ~75 min - the heaviest section per question; calculation-heavy and the most common time-sink
• Buffer + OMR fill-in: ~20 min - transfer answers carefully, double-check fills, attempt marked-for-review questions

There are no sectional time limits - you can move freely between sections. A common strategy is the two-pass method: first pass attempts high-confidence questions across all four sections, second pass tackles the harder Physics / Chemistry ones in your strongest area.

Subject-by-subject breakdown

Each of the four sections has its own personality. Knowing what the section historically tests, and where the marks come from, lets you choose chapters to double-down on. These weightages are indicative trends from past NEET papers; NTA does not publish a fixed blueprint, and chapter coverage varies year to year.

Physics (45 questions, 180 marks)

The hardest section for most candidates and the largest accuracy-killer. Mechanics (Laws of Motion, Work-Energy, Rotation, Gravitation) typically contributes the biggest cluster, with Modern Physics (Atoms, Nuclei, Dual Nature, Semiconductors) a close second. Electrostatics, Current Electricity, Magnetism, Optics, and Thermodynamics round out the remaining marks. Numericals dominate; pure-theory questions are rare. You need formula recall, unit-conversion muscle memory, and fast arithmetic. Most toppers report spending the longest per-question time here.

Chemistry (45 questions, 180 marks)

The Chemistry section is roughly split across Physical, Organic, and Inorganic in a 15-15-15 split, though the ratio shifts a few questions either way each year. Inorganic is high-yield if you have memorised NCERT exceptions, periodic-table trends, and named compounds. Organic rewards mechanism understanding (electrophilic and nucleophilic additions, named reactions like Sandmeyer, Reimer-Tiemann, Friedel Crafts). Physical Chemistry is numerical-heavy: Mole Concept, Equilibrium, Electrochemistry, Solutions, and Chemical Kinetics together typically account for all the calculation questions. NCERT in-text examples and exercises are a reliable source for Chemistry questions.

Botany (45 questions, 180 marks)

Botany is almost entirely NCERT-driven. Plant Kingdom, Morphology, Anatomy, Photosynthesis, Plant Physiology, Reproduction in Flowering Plants, Genetics (Mendelian + molecular basis of inheritance), Ecology, and Biotechnology together form the bulk. Diagrams, life-cycle charts, and classification tables in NCERT Class 11 and 12 Biology textbooks are direct question sources. A clean read of both NCERT volumes plus a focused revision of the diagrams and side-boxes is the most efficient prep strategy. Botany rewards recall over reasoning.

Zoology (45 questions, 180 marks)

Zoology covers Animal Kingdom, Structural Organisation in Animals, Human Physiology (the largest cluster: Digestion, Breathing, Body Fluids, Excretion, Locomotion, Neural Control, Chemical Coordination), Reproduction (Human Reproduction + Reproductive Health), Genetics overlaps, Evolution, and Human Health and Disease. Human Physiology alone accounts for roughly a third of the Zoology questions in most years. Like Botany, Zoology is NCERT-text-heavy with questions often lifted near-verbatim from chapter lines.

Why NEET dropped the optional section in 2024

Until 2023, the NEET UG paper had 200 questions arranged in two sections per subject: Section A (35 compulsory) and Section B (15 questions, of which 10 had to be attempted). The structure gave students a small buffer to skip 5 of 15 Section-B questions per subject. From 2024 onward, NTA scrapped Section B and made all 180 questions compulsory. The total dropped from 200 to 180, the maximum score stayed at 720, and the duration was reduced by 20 minutes (from 3 hours 20 minutes after the COVID-era extension settled).

The practical effect: there is no longer a guaranteed safety net. Every question counts and there is no optional cushion to lean on for weak topics. Question selection has to happen in real time during the paper itself rather than being pre-decided at the section level. For most candidates this means the floor for a competitive raw score has crept slightly upward, and the cost of poor topic coverage is now permanent rather than skippable.

Time management: per-subject pacing

With 200 minutes spread across 180 questions, the average is around 1 minute 7 seconds per question. In practice you should budget unevenly - Biology questions take less than 40 seconds each for a well-prepared student; Physics numericals can swallow 2 to 3 minutes apiece. A realistic per-subject target for a target score of 600+:

• Biology (Botany + Zoology, 90 qs): 45 to 55 minutes total. Aim to finish in one straight pass with confidence checks rather than going back.
• Chemistry (45 qs): 45 to 55 minutes. Solve Inorganic first (fastest), then Organic, then Physical (calculation-heavy) last.
• Physics (45 qs): 70 to 85 minutes. The longest section. Identify your strong chapter clusters and attack those first; flag long-derivation questions for a second pass.
• OMR shading + buffer: 15 to 20 minutes. Reserve at least 12 minutes purely for OMR transfer if you have been solving on the question paper rather than directly on the bubble sheet.

Negative-marking strategy: when to skip

The expected value of a pure 4-option guess is (0.25 × 4) + (0.75 × -1) = -0.25 marks, so blind guessing is mathematically a small loss. The math changes the moment you can eliminate even one option. Two options eliminated gives a 50% accuracy guess with expected value (0.5 × 4) + (0.5 × -1) = +1.5 marks, which is a strong positive bet. Three options eliminated is essentially a free +4. The working rule:

• No options eliminated: skip. The marginal -0.25 EV compounds over many guesses and hurts your overall rank.
• One option eliminated: borderline. Skip unless you are time-rich and confident enough to push your attempted count above 165 of 180.
• Two or more options eliminated: attempt. The math is on your side.
• Read every option: NEET often includes a deliberate near-correct distractor. Eliminating distractors is the primary skill that converts borderline questions to confident attempts.

OMR exam day: how the actual paper feels

NEET UG is one of the few large Indian entrances still on pen-and-paper OMR rather than computer-based testing. The candidate receives a printed test booklet, a separate OMR answer sheet, and a designated ball pen (NTA supplies the pen at the centre and bans your own). The OMR has four bubbles per question; shading must be complete, dark, and only inside the bubble outline. Erasures, partial fills, or stray marks in a neighbouring bubble all count as incorrect answers and attract the -1 penalty even if the underlying answer in your booklet is right.

The OMR transfer step is the silent score-killer. Many students score full marks in their head but lose 8 to 15 marks at the transfer step alone. The standard mistake patterns are: (1) skipping a question on the booklet but forgetting to skip it on the OMR, which shifts every subsequent answer down by one row; (2) shading two bubbles for the same question; (3) running out of time and dark-filling the last 10 to 20 bubbles in a hurry. Practise OMR transfer in at least 10 full-length mocks - it is a motor-skill habit that has to be built, not a theoretical instruction you can read about.

NTA opens NEET centres at 11:00 AM with reporting times typically 30 to 60 minutes earlier. The exam begins at 2:00 PM and runs to 5:20 PM. Candidates arriving after the gate-close time (usually 1:30 PM) are not permitted to write. Plan to arrive at least 90 minutes early on exam day to absorb traffic, parking, and security-line variability.
