NEET is a big test for students who want to become doctors in India. It’s a test to get into medical colleges for courses like MBBS and BDS. In NEET, Biology is super important because almost half the questions in the exam are from Biology. If you’re good at Biology, you can get more marks.

The questions in the Biology part of NEET are usually easy and based on concepts. So, if you understand Biology well, you can score better. To do well, you need to know the NEET Biology Syllabus and how the exam is set.

The National Medical Commission (NMC) recently updated the NEET Biology Syllabus for 2024. They added some new things and removed some old ones. To do well, it’s important to get the latest syllabus from the official website nmc.org.in. This will help you know what topics to study for NEET 2024 and how many marks each topic carries. Knowing this will help you focus more on important topics and do better in the exam.

In this article, we have provided the detailed NEET Biology Syllabus 2024 that mentions the Biology syllabus of class 11 and class 12 that is prescribed for NTA NEET 2024. The medical aspirants can check the chapters and topics from the detailed syllabus mentioned below. Also, check the exam pattern along with unit-wise weightage.

Out of the total 180 questions in the NEET Exam 2024, 90 questions will be asked from Biology as per the following format:

Zoology – 45 Questions – 180 Marks
Botany – 45 Questions – 180 Marks

Subject	Section	No. of Questions	Marks
