To help NEET aspirants, here we bring the Biology syllabus for NEET along with the Biology chapter-wise weightage for the exam based on previous years’ analysis.

NEET Biology Syllabus with NEET Biology Weightage

NEET Biology Syllabus: The Biology section of NEET consists of the highest weightage. As this subject is further segregated into Botany and Zoology, the number of questions from the Biology section is maximum. With the NEET 2025 approaching in May, it is high time aspirants complete the NEET Biology syllabus to ace the exam. Candidates must pay extra focus on this subject.

The National Medical Commission (NMC) has finalised and released the NEET 2025 syllabus. The syllabus has remained the same as last year, when it underwent major changes. While some topics were removed, some were added to the revised NEET syllabus. This article brings the complete NEET 2025 Biology syllabus

Q:   What are the important chapters of the NEET syllabus?

A:

All the chapters are important for NEET 2025. However, the most number of questions are asked from the following chapters of the syllabus of NEET.

Physics:

  • Laws of Motion of System of Practices and Rigid Body
  • Current Electricity Dual Nature of Radiation and Matter
  • Semiconductor Electronics
  • Thermodynamics

Chemistry:

  • Chemical Bonding
  • p-block
  • Coordination Compounds
  • General Organic Chemistry
  • Aromatic Compounds
  • Mole Concepts
  • Thermodynamics
  • Equilibrium

Botany

  • Genetics and Evolution
  • Ecology and Environment
  • Plant Physiology

Zoology

  • Human Physiology
  • Human Reproduction and Reproductive Health
  • Animal Kingdom, Origin & Evolution.

Students must note that these are a handful of important topics for the NEET 2025 syllabus and they should not restrict their preparation to these topics only, and be prepared for all the other chapters and topics carrying a high weightage in the NEET question paper based on past years' exam analysis. 

Q:   Has there been any change in the syllabus of NEET 2025?

A:

No, there has not been any change in the NEET 2025 syllabus. Last year, the NEET syllabus underwent major changes as per the recommendation by the National Medical Commission (NMC).  A number of chapters and topics were removed from Physics, Chemistry and Biology subjects. On the other hand, certain topics and chapters were added and some of the topics were modified. Since such major changes were brought in to last year's NEET syllabus, the NEET 2025 syllabus is unchanged. 

NEET syllabus 2025 has been released officially by NMC in December 2024. Hence, students preparing for NEET 2025 should start preparing, or continue their preparation based on last year's NEET syllabus. Even if some changes are introduced to the NEET 2025 syllabus, those would not be something major. 

Q:   What is the syllabus of NEET UG?

A:

NEET UG Syllabus is divided among 4 sections- Physics Chemistry Zoology Botany All these 4 sections hold same marks for the examination and all the sections have 45 questions to be attempted in 45 minds itself. From the link NEET Exam Syllabus you can check the complete syllabus and important topics for 11th and 12th for Physics, Chemistry, and Zoology & Botany. The NEET syllabus underwent major changes last year and this year it has remained the same. The NEET syllabus is the same as the Board exam syllabus. Hence, it is mandatory for students to study and prepare Class 11 and Class 12 syllabus thoroughly to complete NEET syllabus. Unlike previous years, the NEET subject-wise syllabus is not segragated into Class 11 and Class 12 topics, and experimental subjects have been added to Physics subject.

Q:   Is the NEET syllabus tough?

A:

The NEET syllabus is same as that of Class 11 and Class 12 CBSE Board exam syllabi. Hence, it is not that difficult or students need not study anything additional apart from their school or Board exam studies. However, the difficulty level of the exam depends on the question types, which is generally tricky in nature, which makes the difference in the difficulty level.

The best way to tackle the NEET syllabus is through revision and taking as many mock tests as possible. According to experts and previous years' NEET analysis, Physics section is the toughest followed by Chemistry and Biology. Moreover, toughness is subjective and it depends on the preparation level and aptitude of students.

Q:   What is the Biology syllabus for NEET?

A:

The Biology syllabus for NEET has undergone changes based on the recommendations by the National Medical Commission (NMC). Although earlier the NEET syllabus for Biology was categorised into Class 11 and Class 12 syllabus, it has now been merged. The units of the NEET 2024 Biology syllabus is given below. 

Unit I: Diversity in Living World

Unit II: Structural Organisation in Animals and Plants

Unit III: Cell Structure and Function

Unit IV: Plant Physiology

Unit V: Human Physiology

Unit VI: Reproduction

Unit VII: Genetics and Evolution

Unit VIII: Biology and Human Welfare

Unit IX: Biotechnology and Its Applications

Unit X: Ecology and Environment

Q:   Why was the NEET 2024 syllabus changed?

A:

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, 

Q:   Which chapters carry a high weightage in NEET Physics syllabus?

A:

The chapters carrying high weightage in the NEET Physics syllabus are as follows:

  • Thermodynamcs
  • Current Electricity
  • Dual Nature of Radiation and Matter
  • Electromagnetic Waves
  • Semiconductor Electronics: Materials, Devices and Simple Circuits

The following table brings the chapter-wise weightage of NEET Physics syllabus based on previous year's analysis.

Q:   What is the ratio of the NEET syllabus from Class 11 and Class 12?

A:
There is no specific or defined ratio of Class 11 and Class in which questions are set from the NEET syllabus. It varies from year to year. Based on the previous year NEET question paper analysis, it has been observed that the ratio of the Class 12 syllabus is higher than that of Class 12 syllabus. Here we present the subject-wise ratio of Class 11 and Class 12 NEET syllabus based on last year's analysis. Physics Class 11 - 42% Class 12 - 58% Chemistry: Class 11 - 42% Class 12 - 58% Biology: Class 11 - 53% Class 12 - 47%. .

Note: The above table carries topic-wise weightages based on last year's NEET exam. Candidates may use it for reference by omitting the removed topics.

Best Books to Prepare for NEET Biology Syllabus

The best books to prepare for the NEET Biology syllabus are given below:

  • NCERT Biology Books for Class 11 and Class 12
  • Biology by Trueman (Volume 1 and 2)
  • Objective Botany by Ansari
  • Pradeep Guide on Biology
  • G R Bathla publications for Biology

  • Together with Biology by S Venugopal

NEET 2024 Analysis of Biology Section

As per the NEET 2024 analysis, Biology questions in NEET 2024 were 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 following infographic brings the weightage of NEET Biology questions for Class 11 and Class 12.

NEET 2025 will be conducted tentatively in the first week of May 2025. The NEET exam pattern and syllabus are likely to remain the same as last year. The exam will be conducted for a duration of 200 minutes and the NEET question paper will carry 200 questions, out of which 180 questions have to be attempted. Each subject will be divided into two sections. The first section will have 35 questions all of which are compulsory to attempt. The second section will have 15 questions, out of which 10 questions need to be attempted.
