NEET Biology Syllabus 2026 for Botany & Zoology
Commonly asked questions
Yes, NCERT books are sufficient to complete the NEET syllabus. A number of past years' NEET toppers have claimed that they referred only to NCERT books for preparation. NCERT textbooks act as the base to complete the syllabus and develop conceptual clarity and understanding of the topics and chapters. However, for practice purposes, students may refer to other books and resources as well. It is advised that while starting the NEET preparation, candidates refer to the NCERT books and move towards other books and advanced resources after that.
No, the topic or chapter on earthworm is not included in the NEET Biology syllabus. The NEET syllabus underwent changes wherein certain topics were removed and various topics have been added from other state Boards. In the NEET revised syllabus, there was no mention of the Earthworms topic. Under the unit of Structural Organisation in Animals and Plants, the topic of 'Nervous and reproductive of an insect and Frog.' Based on last year's syllabus, it is estimated that the insect is cockroach, along with frog. Hence, it can be estimated that the Earthworm topic will not be included in the NEET Biology syllabus as well.

The National Testing Agency (NTA), had clarified the reason behind changing the NEET 2024 syllabus. NTA stated, "Due to the COVID-19 scenario, various School Boards deleted portions of each subject's syllabus. The deleted portion is still not being taken back by these Boards. The deletions were not uniform across various boards. Hence, a number of requests were received by the NTA for the revision of the syllabus." Last year, before the NEET exam, several students and parents asked NTA to release the rationalised NEET syllabus. Since the syllabus of NEET was already released before the rationalisation took place,
The Chemistry section of NEET is divided into three sub-sections: Physical, Organic and Inorganic. The least number of questions are from Physical Chemistry. Inorganic and Organic Chemistry chapters have almost similar weightage. In terms of the ratio of Class 11 and Class 12 syllabus of NEET the latter has a higher weightage. The total number of questions asked from the Chemistry section will be 50, out of which 45 questions have to be attempted. The topics carrying high weightage in NEET based on last year's analysis are given in the table below.
| NEET Chemistry Topics | Number of Questions |
|---|---|
| Organic Chemistry | 18 |
| Inorganic Chemistry | 17 |
| Physical Chemistry | 15 |

NEET Biology Syllabus 2026 Analysis
As per the NEET exam analysis, Biology questions in NEET are mostly NCERT-based. Questions were mostly from topics such as Human Physiology, Genetics, and Plant Physiology. Unlike previous years, this year's question papers featured six figure-based and three direction-based questions, along with 30 'match the following' and 17 statement-based questions. As 30 per cent of the questions were of the 'match the following' type, some students found the paper a bit lengthy. The infographic brings the weightage of NEET Biology questions for Class 11 and Class 12.

How to Prepare for NEET Biology 2026?
Biology is one of the easiest subjects of NEET and studying for the NEET 2025 Biology syllabus would require sincerity and determination, along with conceptual clarity. Here are a few tips for NEET 2025 Biology preparation.
- Refer to the right books: Students must complete the NCERT Biology textbooks first to develop the foundational knowledge, or to complete fundamental preparation. After that, they may move on to other advanced books,
- Use visual learning techniques: Since Biology is all about diagrams, using visual learning techniques like using flashcards, drawing diagrams and labelling important parts, making notes and highlighting the important points, to name a few.
- Solving NEET previous years questions, mock tests: NEET question papers give the right exposure to students in terms of the question types and topics covered in the NEET Biology syllabus. It also serves as a proper practice material, along with taking regular NEET mock tests.
- Regular revision: Regular revision is the key to any exam preparation. As soon as you complete a topic, you should revise and brush up on the knowledge acquired. Regular revision will ensure that you do not forget the topics that you had prepared a while ago.
- Make a timetable: Since NEET preparation involves studying multiple subjects, it is of utmost importance to strike a balance. Here, preparing a timetable comes in handy, wherein students will allot a proper schedule to study, revise, and practice the NEET Biology syllabus.
