NEET 2025 Syllabus - FAQs

Will NEET 2025 syllabus be reduced?

NEET 2025 syllabus is expected to be the same as the NEET 2024 syllabus, which is reduced by NMC, considering the reduction of syllabus by various boards including CBSE, ICSE and State Boards. New NCERT textbooks could be another reason for reduction in NEET syllabus.

How many chapters are there in NEET 2025 syllabus?

There are a total of 79 chapters in the NEET 2025 syllabus covering all 3 subjects Physics, Chemistry and Biology. Previously, NEET-UG syllabus included 97 chapters.

What are the important chapters in NEET syllabus?

Many students who start their NEET preparation late have a lack of time to complete the full syllabus. They can try to cover important chapters in NEET syllabus.

Is earthworm and frog in NEET syllabus?

Not earthworm, but frog is included in the NEET syllabus. In the chapter Structural Organisation in Animals, there is only a brief account on the morphology, anatomy and function of different systems i. e digestive, circulatory, respiratory, nervous and reproductive system of an insect and a frog.
