The National Medical Commission NMC has released the Biology Syllabus for students aspiring for NEET 2025.
As of 2025, the distribution of the Biology section of the NEET would be 100 questions carrying a total of 360 marks, which is 50% of the entire examination.
The NEET 2024 Biology syllabus has undergone reductions, with certain topics removed. For simplification which remains same for the year 2025.
- In the chapter "Diversity in the Living World," several topics, including the three domains of life, tools for studying taxonomy (museums, zoos, herbaria, and botanical gardens), and classification of flowering plants up to the class level, have been deleted.
- From "Structural Organisation in Animals and Plants," content related to morphology, modifications, tissues, and anatomy of flowering plants, together with animal tissues, are deleted.
“ Previous years’ have witnessed a huge rise in NEET UG applications, with as many as 20 lakh students appearing in 2024, compared to 18.7 lakh in 2023 and 16.1 lakh in 2022".

Will NEET 2025 Be Held Twice?
There have been talks about conducting NEET multiple times each year, but no official confirmation has so far been provided for NEET 2025. It's wise to keep checking the official NTA announcements tide to get the right and accurate information at all times.
NEET Examination Pattern 2025
As of now, NTA has recently released NEET Examination Pattern for the academic year 2025, for which a notice was already published on October 17, 2024, clarifies that the examination pattern will revert to the original pattern of five questions in Section B with all to be attempted by the candidates in a single attempt.
There are two parts of Biology: Botany and Zoology. Each part is divided into A and B. There are a total of 35 questions in A with each carrying 4 marks for a total of 140 marks. Section B has 15 questions; however, students are required to answer only 10, with each carrying 4 marks for a total of 40 marks. The exam pattern is the same for both Botany and Zoology, thus giving 180 marks for each part.
Here is the exam pattern of NEET 2025:
| Subject | Sections | Number of Questions | Questions to Attempt | Marks per Question | Total Marks |
|---|---|---|---|---|---|

NEET 2025 Biology Preparation Plan
A well-organized study schedule is necessary for the NEET 2025 exam, particularly for Biology, since it accounts for 50% of the total exam weight (90 questions). A thorough NEET Biology preparation strategy is provided below:
- Form a study plan in which you spend 2 or more hours a day on Biology starting from now till a month before the exam.
- Then in January, start taking at least one full mock exam a week to make sure your stamina for the test is built and you sort out your timing issues before the real exam.
- Don’t neglect the NCERTs as they are the basis of every competitive exam out there, including NEET. Questions mostly come straight from these texts.
- DIAGRAMS, FLOWCHARTS AND TABLES! Try to practice these as much as you can because they really improve the memory of complex topics.
- Do not forget to set aside time to revise the concepts and areas you may be weaker in. Set a day each week to revise what you learnt.
