If you are preparing from a book printed before 2023, a coaching module passed down from an older cousin, or a big question bank, a part of what you are studying is no longer on the NEET paper. The National Medical Commission revised the syllabus for NEET 2024 to line it up with the rationalised NCERT books, and the notices for 2025 and 2026 kept the same content.
That is good news. It means fewer chapters, and a week you might have spent on Surface Chemistry can go on something that will actually be asked. Here is what went, subject by subject, and what came in.
Last checked on 27 October 2026 against the NMC's NEET (UG)-2026 syllabus notice of 22 December 2025. The NEET 2027 syllabus has not been published yet; the NMC usually releases it around December, and this page will be updated if anything changes.
Whole chapters that are gone
Botany
- Transport in Plants
- Mineral Nutrition
- Reproduction in Organisms (the separate chapter on asexual reproduction)
- Strategies for Enhancement in Food Production
- Environmental Issues
Zoology
- Digestion and Absorption
- Animal husbandry, dairy, poultry, fisheries and apiculture
Chemistry
- States of Matter
- Hydrogen
- s-Block Elements
- Environmental Chemistry
- Solid State
- Surface Chemistry
- General Principles and Processes of Isolation of Elements (metallurgy)
- Polymers
- Chemistry in Everyday Life
Physics
- Physical World
If a chapter on this list is in your book, skip it for NEET.
Smaller topics removed from chapters that are still in
These are the easy ones to miss, because the chapter itself is still on the syllabus.
Botany
- The Living World: taxonomical aids — herbarium, botanical gardens, museums, zoological parks and keys — and the three domains of life.
- Plant Kingdom: alternation of generations and life cycles.
- Morphology of Flowering Plants: the families Solanaceae and Liliaceae.
- Anatomy of Flowering Plants: secondary growth.
- Plant Growth and Development: seed dormancy, vernalisation and photoperiodism.
- Ecosystem: succession, nutrient cycles and ecosystem services.
Zoology
- Structural Organisation in Animals: cockroach and earthworm. The frog is studied instead.
- Neural Control and Coordination: the reflex arc and the sense organs (eye and ear).
Physics
- Rolling motion; geostationary and polar satellites; Poisson's ratio; Reynolds number.
- Heat engines and refrigerators; black-body radiation, Stefan's and Wien's laws, Newton's law of cooling.
- Damped and forced oscillations; the Doppler effect.
- The potentiometer; the colour code of resistors; the cyclotron; Earth's magnetism.
- The human eye, dispersion and scattering; resolving power; the Davisson–Germer experiment.
- Radioactivity (decay law, half-life); transistors and amplifiers.
Chemistry
- Specific p-block compounds such as borax, diborane, silicones, interhalogens and xenon compounds. The general trends of Groups 13 to 18 stay.
- Early atomic models (Thomson, Rutherford); the third law of thermodynamics; corrosion.
What was added — and older books will not have
- Physics: a unit of Experimental Skills — vernier calipers, screw gauge, metre bridge, the resonance tube, p-n junction and Zener diode characteristics and more. Expect a question or two on how an experiment is done and read.
- Chemistry: a unit of Practical Chemistry — salt analysis, titrations, preparations of inorganic and organic compounds, enthalpy experiments.
- Botany: five plant families by name — Malvaceae, Cruciferae, Leguminosae, Compositae and Gramineae.
- Zoology: the frog; the classification of enzymes; dengue and chikungunya under human diseases.
These are worth an hour each precisely because many question banks have little on them.
A note if you are also preparing for JEE
Physics and Chemistry are shared with JEE, and JEE has its own syllabus. Several topics NEET dropped — the Doppler effect, the potentiometer, Solid State, the s-block — are still tested in JEE (Advanced). If you are preparing for both, do not delete those chapters; just do not spend NEET revision time on them.
Do old questions on removed topics hurt?
Practising a question on a removed topic does not cost you marks, but it costs you time — and in the last six months time is the only thing you are short of. When you go through past papers, mark the questions from removed topics and move on. On Nikaalle, questions from removed NEET topics are not set in NEET practice or mocks; the past-paper section still shows them as they were asked, so the papers stay complete.
Where to check the full list
The chapter-by-chapter list, with what is in each subject today, is on our NEET syllabus 2027 page. The official source is the NMC's NEET (UG) syllabus notice, which the NTA links from neet.nta.nic.in. When the NEET 2027 notice is published, compare it with this list before you change your plan.
Nikaalle's NEET plan, practice and mocks follow the current syllabus only, free to start, from a non-profit trust. [Start here](/register?exam=NEET).
