Preparing for NEET 2026 requires more than just hard work — it demands smart work. With 180 compulsory questions (+4/–1 marking) and Biology making up 50% of marks, focusing on high-scoring chapters can be the difference between a 500 and a 650+ score. This blog gives you a subject-wise priority list, a Top 15 chapter checklist, and both two-year and one-year study plans tailored for NEET aspirants.
| Component | Details |
| Mode | Pen-and-paper OMR |
| Total Questions | 180 (all compulsory) |
| Subject Split | Physics – 45, Chemistry – 45, Biology – 90 |
| Marking Scheme | +4 for correct, –1 for wrong |
| Duration | 3 hours |
NMC rationalisation has trimmed redundant topics, placing more emphasis on NCERT-based core areas like Genetics, Human Physiology, Ecology, Modern Physics, and Chemical Bonding. Why it matters: With fewer distractions, mastering chapter-wise weightage is more crucial than ever.

Biology is the backbone of NEET — 90 questions worth 360 marks.
| Chapter | Approx. Weightage | Why Important |
| Genetics & Evolution | 18–25% | Consistently 15–18 Qs in NEET |
| Human Physiology | 13–20% | Covers digestion, respiration, circulation |
| Ecology & Environment | 16–19% | 12–15 direct NCERT-based Qs |
| Biotechnology | 12–16% | Application-heavy, NCERT line-based |
80–85% of Biology questions come directly or indirectly from NCERT lines.

Physics scares many aspirants, but weightage analysis shows repeated scoring buckets.
| Topic Cluster | Chapters to Prioritize |
| Electrodynamics | Current Electricity, Magnetism, Circuits |
| Modern Physics | Atoms, Nuclei, Semiconductor Electronics |
| Mechanics | Laws of Motion, Work-Energy-Power, System of Particles, Rigid Body |
| Optics & Thermodynamics | Ray & Wave Optics, Heat Transfer, Thermodynamics |
Pro Tip: Maintain a formula revision sheet and solve 25–30 MCQs daily from these areas.
Here’s the unified high-priority list:
Covering just these 15 can secure 400–450+ marks if mastered.

Revision Cycle:
Tip: Build a night card system — write 10 errors/day on flashcards and revise next morning.
| Timeline | Tasks | Focus Areas |
| Months 1–4 | Finish Class 11 & 12 NCERT high-weightage chapters | Genetics, Human Physiology, Ecology, Chemical Bonding, Thermodynamics, Modern Physics |
| Months 5–8 | PYQ practice + sectional tests | 45Q Physics, 45Q Chemistry, 90Q Biology |
| Months 9–12 | Intensive revision + mocks (2–3/week) | Speed, accuracy, negative marking control |
Tip: In one year prep, stick to NCERT + PYQs + coaching modules — avoid too many reference books.
NEET 2026 isn’t about covering everything equally — it’s about prioritizing high-scoring chapters. Focus on the Top 15 chapters, follow the one-year or two-year study roadmap, and combine NCERT mastery with consistent mock tests. If you plan smartly, 650+ marks is achievable. Action Step: Start with NCERT Biology + Top 5 Physics & Chemistry topics this week and build momentum.
The most important Biology chapters for NEET 2026 are Genetics and Evolution, Human Physiology, Ecology and Environment, and Biotechnology. Together, these units carry more than 50% of the Biology weightage, meaning almost half of the Biology questions will come from them. For example, Genetics alone often gives 10–12 questions, while Ecology contributes 12–15 questions every year. If you master these four units directly from NCERT (line-by-line, diagrams, and tables), you can secure 150+ marks from Biology itself.
Yes, Modern Physics is extremely important. On average, 6–8 direct questions appear from Modern Physics, including topics like Atoms, Nuclei, and Semiconductor Electronics. These questions are often straightforward if you have practiced the NCERT examples and solved previous year questions. Many students find Modern Physics easier compared to lengthy Mechanics, so it’s considered a high-scoring Physics unit.
Yes, but selective study needs to be smartly planned. If you completely master the Top 15 high-weightage chapters (such as Genetics, Ecology, Human Physiology, Chemical Bonding, Coordination Compounds, Modern Physics, and Current Electricity) and revise NCERT daily, you can score 550–600+ marks. However, to go beyond 600 and aim for 650+, you should also solve NCERT Exemplar, past 10 years’ PYQs, and full-length mocks to ensure accuracy under exam pressure.
Biology → 100% Yes. NEET Biology is almost completely based on NCERT. Every line, diagram, and table from Class 11 & 12 Biology NCERT is important. Many toppers highlight that reading NCERT 5–6 times is the single biggest reason for their Biology scores.
Physics & Chemistry → Partially. For Physics, NCERT covers theory well, but you need extra problem-solving practice from coaching modules or standard books like HC Verma and DC Pandey. For Chemistry, NCERT is enough for Inorganic, but Physical and Organic require formula drills, mechanism practice, and question banks.
You should dedicate at least 3–4 months for structured revision before NEET 2026. In this period, your focus should shift from learning new topics to:
1. Full-syllabus mock tests (2–3 per week).
2. Error logbook analysis – reattempt questions you got wrong.
3. Biology NCERT re-reading (at least 2–3 times in revision months).
4. Quick formula sheets for Physics and Chemistry.
This ensures you don’t just remember concepts but also recall and apply them under time pressure.
