Most Repeated Questions in NEET Biology, Chemistry and Physics, Chapter-Wise Weightage & Important Topics
Preparing for NEET becomes much easier when you know which chapters carry the highest marks and which questions get repeated every year.
The NEET exam may change slightly every year, but the core concepts and high-weightage chapters remain the same. Understanding these patterns helps students plan better, score higher, and feel more confident during the exam.
In this blog, we break down the most repeated questions, chapter-wise weightage, and important topics for all three subjects — Biology, Chemistry, and Physics. If you are preparing for NEET 2026, this guide will help you focus on what actually matters.
Most Repeated Question in NEET
1. NEET Biology Most Repeated Questions & Important Chapters
Biology forms 50% of the NEET paper (90 questions), making it the most important subject. A large number of questions are directly repeated every year — sometimes with slight changes in wording.
High-Weightage Biology Chapters (2024–2025 Trend)
- Human Physiology – 15 to 20 questions
- Genetics & Evolution – 12 to 14 questions
- Plant Physiology – 8 to 10 questions
- Ecology & Environment – 10 to 12 questions
- Reproduction (Plant & Human) – 8 to 10 questions
- Biotechnology – 6 to 8 questions
Most Repeated Questions in Biology
These concepts appear almost every year:
Human Physiology
- Structure and function of the heart, blood circulation
- Nephron structure and urine formation
- Mechanism of muscle contraction
- Hormones of the endocrine system
Genetics & Evolution
- Mendel’s laws, dihybrid and monohybrid crosses
- Genetic disorders (Thalassemia, Sickle-cell anemia)
- Hardy-Weinberg principle
Ecology
- Population interactions (predation, competition, mutualism)
- Pyramid of energy, ecosystem flow
- Biodiversity hotspots and conservation methods
Reproduction
- Menstrual cycle, hormonal regulation
- Pollination, double fertilization in plants
- Gametogenesis
Biotechnology
- DNA cloning, PCR steps
- Restriction enzymes
- Applications of biotechnology in health
2. NEET Chemistry Most Repeated Questions & Important Chapters
Chemistry has 45 questions and is divided into Physical, Organic, and Inorganic Chemistry. Many questions repeat in concepts or formats.
High-Weightage Chemistry Chapters
- Physical Chemistry – 12 to 15 questions
- Organic Chemistry – 15 to 18 questions
- Inorganic Chemistry – 12 to 15 questions
Most Repeated Chemistry Questions
Physical Chemistry
- Mole concept, limiting reagents
- Electrochemistry (Nernst equation, cell potential)
- Thermodynamics (ΔH, ΔG, spontaneity)
- Kinetics (rate law, order of reaction)
Organic Chemistry
- General Organic Chemistry (GOC) basics
- Isomerism, optical activity
- Named reactions: Aldol condensation, Cannizzaro reaction, Friedel-Crafts reactions
- Reaction mechanisms: nucleophilic and electrophilic substitutions
Inorganic Chemistry
- Periodic trends
- Chemical bonding (VSEPR, hybridisation)
- Coordination compounds: IUPAC names, bonding
- p-block and d-block elements (oxidation states, reactions)
3. NEET Physics Most Repeated Questions & Important Chapters
Physics is often the toughest part for NEET aspirants. However, NEET physics questions are mostly formula-based, so repeated practice gives excellent results.
High-Weightage Physics Chapters
- Mechanics – 10 to 12 questions
- Electrodynamics – 8 to 10 questions
- Modern Physics – 6 to 8 questions
- Optics – 4 to 5 questions
- Thermodynamics & Kinetic Theory – 3 to 4 questions
Most Repeated Physics Questions
Mechanics
- Newton’s Laws of Motion
- Work, Energy & Power
- Circular motion
- Rigid body and rotational motion
- Gravitation (escape velocity, satellites)
Electrodynamics
- Current electricity (Ohm’s law, resistors in series/parallel)
- Electrostatics (Coulomb’s law, electric field, potential)
- Magnetism (Lorentz force, magnetic field)
- AC circuits (LC, RC circuits)
Modern Physics
- Photoelectric effect
- Atomic models
- Nuclear reactions
Optics
- Mirrors & lenses formulas
- Young’s double-slit experiment
4. How to Use Repeated Questions & Weightage for NEET 2026 Preparation
Here is how toppers use this information:
- Prioritize High-Weightage Chapters: Complete them first, revise them more often, and solve extra questions.
- Practice Previous Year Questions (PYQs): Around 60–70% of NEET questions follow previous-year patterns.
- Make Formula & Concept Sheets: Especially useful for Physics and Physical Chemistry.
- Revise NCERT Thoroughly: Most Biology questions come directly from NCERT.
- Take Mock Tests Regularly: Analyze mistakes and adjust your preparation strategy.
How Unwal Pacific Helps with Strategic Preparation
At Unwal Pacific, we provide students with comprehensive analysis of the NEET important chapters and repeated question patterns.
Our faculty designs focused study plans based on NEET chapter-wise weightage, ensuring students spend time on topics that matter most. We regularly update our teaching methods based on NEET previous year trends, helping students prepare efficiently for NEET 2026.
Final Thoughts
Understanding NEET’s most repeated questions and chapter-wise weightage helps you prepare strategically. Focus on high-yield topics in Biology’s Human Physiology, Chemistry’s Organic reactions, and Physics’ Mechanics and Electrodynamics.
However, don’t ignore other chapters completely. With smart preparation focusing on important NEET topics asked every year and thorough NCERT mastery, you can maximize your NEET 2026 score efficiently!
