NEET Deleted Chapters 2026: Physics, Chemistry & Biology (Official Update)

The NEET examination syllabus has once again been rationalised, which has caused confusion and concern amongst the aspirants. With lakhs of students gearing up big time for NEET 2026, it is no longer optional to understand the NEET 2026 deleted syllabus, but is essential. This blog provides you with a proper subject-wise, chapter-wise deleted chapter list, along with the reason for these changes and helps you plan smartly without wasting time on irrelevant parts.

NEET 2026 Deleted Syllabus - Latest Official Update

The NEET 2026 deleted syllabus is based on the revised curriculum of the NCERT that is followed in Classes 11 and 12. As a result, some of the chapters from Physics, Chemistry and Biology are no longer a part of the official preparation scope.

The update has been done through syllabus documents as per NCERT rationalisation and in the exam guidelines issued by the authorities. While the NTA NEET official notification does not mention the deleted chapters separately, the topics that have been removed are clearly not included in the prescribed NCERT textbooks.

These deletions directly affect the way the aspirants plan their preparation. Students who don't know what they are in for are in danger of spending months on chapters that won't contribute to their score. Understanding the deleted syllabus helps to save time and focus on high-weightage units for candidates to help them prepare more strategically for NEET 2026.

Why Chapters Were Deleted from the NEET Syllabus 2026?

NCERT Rationalisation of Syllabus

NCERT has made changes in its syllabus to cut down on the repetitive content and dated examples, and topics that are not too advanced for the foundation level learning. As NEET is strictly based on the NCERT textbooks, any chapter deleted or truncated by NCERT directly affects the exam syllabus. This rationalisation is so that there is uniformity across boards and students are not loaded with too much content that does not add much conceptual value.

Focus on Concept-Based Learning

Another key cause for the reduction in the syllabus is the move towards conceptual clarity. Instead of mugging up long theoretical chapters, NEET now focuses on core concepts, applications and analytical thinking. The NEET Chemistry syllabus changes and reductions in Biology is a part of this move. The goal is to test how well students grasp concepts and not how much content they can remember.

The NEET Deleted Chapters 2026 - Subject Wise List

The deleted syllabus has an impact on all three subjects, namely Physics, Chemistry, and Biology in both Class 11 and Class 12. However, the level of deletion varies from subject to subject. Physics has had some mathematically intensive or less frequently tested units removed, Chemistry reduced some of the descriptive parts, and Biology has had factual-heavy chapters cut down. Below is a detailed breakdown of each subject to help the aspirants to align their preparation properly.

NEET Deleted Chapters 2026 - Physics

Physics is a concept-oriented subject and requires good basics and regular practice of problems. According to NEET Deleted Syllabus 2026, to match the exam syllabus with the revised NCERT textbooks, multiple theory-heavy and limited-application topics have been deleted.

Chemistry has also experienced a well-organized reduction under NEET Deleted Syllabus 2026, with the goal of cutting down topics that are based on factual recall and descriptive learning. Instead of testing content related to memory, the revised syllabus urges students to work more on core concepts and questions related to application.

Biology has the highest weightage in the NEET exam and hence, it is a deciding subject for ranking in NEET. Under the NEET Deleted Syllabus 2026, several theory-heavy and environment-oriented topics have been removed to make the learning process easier and less burdensome for the students.

Many aspirants especially seek the NEET Biology Deleted Syllabus 2026 and the overall NEET 2026 deleted syllabus to avoid confusion while revising. Most of the removed parts are in descriptive chapters and organism-based classifications that previously required much memorisation.

Deleted Topics in NEET Biology (2026)

The NEET Deleted Syllabus 2026 in Biology helps students to concentrate better on high-priority topics like human physiology, genetics, biotechnology, and cell biology that have a higher number of questions and a higher question weightage in the exam.

Biology Weightage Warning for NEET Aspirants

Biology still adds up to 50% of the overall NEET score. Even with the deletions, it is important for students to focus on NCERT line-by-line reading because most of the questions from Biology are direct and are highly NCERT-based.

Will Questions come from Deleted Chapters in NEET 2026?

Officially, questions should not be asked from deleted chapters as per NTA NEET official notification and the NCERT-aligned syllabus. However, past-year trends show that there is a possibility for conceptual overlap. Sometimes, the questions are questions designed to test ideas that link deleted topics with retained chapters.

The risk is low but not zero. Therefore, basic concepts of deleted chapters should be understood by the aspirants without investing heavy revision time. Smart preparation means targeting active chapters when being conceptually aware of ideas.

How Should NEET Aspirants Study After Deleting Chapters?

Concentrate on the Chapters of High Weightage

Use NEET past years' solved papers to find out which chapters tend to generate questions. Units such as Human Physiology, Electrostatics, Organic Reaction Mechanisms etc. should get maximum attention.

Review Overlapping Concepts

Some of the deleted chapters have concepts that are similar to retained units. Instead of full preparation, revise definitions, formulas and applications which are common to the current syllabus.

Smart Revision Strategy

Don't Panic-try to read deleted chapters near the exam. Use NCERT-based mock tests and revise only what is prescribed formally to maximise score efficiency.

Common Mistakes Made By Students After Syllabus Reduction

Many students neglect the basics, thinking that deleted chapters are of no use. Others make too many leaps, missing links in concepts. Another common mistake is to rely on outdated sources rather than keep track of official updates of syllabus. Staying with the current NCERT syllabus is very important to save oneself from negative surprises.

Final Takeaway for NEET 2026 Aspirants

The NEET syllabus reduction isn't a disadvantage - it's an opportunity. By being aware of the NEET 2026 deleted syllabus, students can study smarter, revise faster, and prevent burnout. Concentrate on high-yield chapters, follow NCERT strictly and keep a track of official updates regularly. It is strategic preparation and not excessive studying that differentiates the top rankers from the rest. Be consistent, be informed, be confident in the process.
