NEET Most Repeated Questions Last 10 Years (2015-2025): High Weightage Topics & PYQ Analysis for NEET 2026
Preparing for NEET 2026? If you want to score 600+ marks, you must master the NEET most repeated questions last 10 years. Exact questions rarely repeat verbatim, but core concepts, NCERT lines, diagrams, and question patterns appear again and again. In the last decade (2015–2025), almost 30–40% of the paper comes from high-weightage topics that repeat every year.
In this ultimate guide, we bring you a complete NEET PYQ analysis 2015-2025 with subject-wise most repeated concepts, chapter weightage, and proven preparation strategy. This post is updated for NEET 2026 aspirants and is 100% based on official papers and expert analysis from top coaching institutes.
Why NEET Most Repeated Questions Matter for NEET 2026?
NEET is highly predictable. NTA follows NCERT closely, and certain topics appear in 8–10 out of the last 10 papers. Solving previous year questions (PYQs) helps you:
- Understand exact question patterns
- Save time during the actual exam
- Score 150–200 extra marks easily
- Focus only on high-weightage chapters (80% questions come from just 40% syllabus)
Pro tip: Biology alone gives 360 marks — and 60–70% of it is directly from repeated NCERT-based concepts!
Biology: Most Repeated Topics in NEET Last 10 Years (Highest Weightage)
Biology is the scoring goldmine in NEET. Over the last 10 years, Human Physiology, Genetics, and Ecology dominate with 35–40 questions every year.
Top Repeated Units in Biology
- Human Physiology (10–12 questions every year): Heart structure & ECG, Nephron & urine formation, Sliding filament theory, Respiratory exchange of gases, Digestive enzymes & hormones.
- Genetics & Evolution (8–10 questions): Mendel’s laws, Pedigree analysis, Genetic disorders (Sickle cell, Thalassemia, Down syndrome), Hardy-Weinberg principle, Lac operon, DNA replication & transcription.
- Plant Physiology (6–8 questions): Photosynthesis (C3 vs C4, Calvin cycle), Respiration (Glycolysis & Krebs cycle), Plant growth regulators (Auxin, Gibberellin, Ethylene).
- Ecology & Environment (6–8 questions): Population interactions, Ecological pyramids, Biodiversity conservation, Ozone depletion & greenhouse effect.
- Biotechnology & Reproduction (5–7 questions): PCR, Restriction enzymes, Bt cotton, Plasmids (pBR322), Human reproductive health.
Must revise: All NCERT diagrams — Nephron, Sarcomere, Calvin cycle, Lac operon, and Ecological pyramids appear almost every single year.
Chemistry: High Weightage & Most Repeated Concepts
Chemistry contributes 180 marks. Inorganic and Organic sections have the highest repetition rate.
Top Repeated Chapters in Chemistry
- Inorganic Chemistry (12–15 questions): Coordination compounds (CFT, magnetic properties), p-block elements (Group 15–18), d & f-block, Periodic table trends, Chemical bonding (VSEPR & hybridization).
- Organic Chemistry (12–14 questions): General Organic Chemistry (resonance, inductive effect), Named reactions (Aldol, Cannizzaro, Williamson), Biomolecules (proteins, carbohydrates, nucleic acids), Haloalkanes, Alcohols, Aldehydes & Ketones.
- Physical Chemistry (10–12 questions): Mole concept, Thermodynamics (1st & 2nd law), Chemical equilibrium, Electrochemistry (Nernst equation), Chemical kinetics.
Pro tip: Memorise NCERT exceptions and reaction charts. Biomolecules and Coordination compounds are the most scoring repeated topics.
Physics: Most Repeated Numerical & Conceptual Topics
Physics is concept + numerical heavy. Mechanics and Electrodynamics repeat maximum.
Top Repeated Units in Physics
- Mechanics (12–15 questions): Laws of motion, Work-energy-power, Rotational motion (moment of inertia, rolling), Gravitation, Projectile motion.
- Electrodynamics (10–12 questions): Electrostatics (Gauss law, capacitors), Current electricity (Kirchhoff’s laws, Wheatstone bridge), Magnetic effects & EMI, AC circuits (LCR resonance).
- Optics & Modern Physics (8–10 questions): Ray optics (lens/mirror formula), Wave optics (Young’s double slit), Photoelectric effect, Bohr’s model, Semiconductors.
- Thermodynamics (4–6 questions): PV diagrams, Heat engines, 1st & 2nd law.
Must practise: Numerical-based questions on Rotational motion, Electrostatics, and Optics — these patterns repeat every year.
