NEET syllabus is the first thing that must be understood by an aspirant who is planning to prepare for NEET 2021. Knowing the NEET syllabus 2021 is one thing, and understanding the contents of that syllabus is quite another. By contents of the syllabus, we mean the individual topics and subtopics that fall in that syllabus.

It is for this reason that we recommend the student to understand the syllabus by getting into the details of the different topics and subtopics, by understanding the different types of questions that have come from those topics and subtopics, and by understanding their relevance in the context of the latest NEET exam pattern.

Before we go ahead into the nitty-gritty of the NEET syllabus, we would let you know that there is an official syllabus of NEET released by the NTA and the syllabus that you see here is in accordance with that.

The NEET exam tests the aspirants in three areas

  • Physics
  • Chemistry 
  • Biology

We will try to understand the syllabus for NEET Biology in this doc.

NEET Syllabus: Biology

We can categorise the Biology syllabus is two parts:

  • Botany
  • Zoology

The NEET Biology section contains 90 questions mounting to a total of 360 marks. It accounts for 50% of the exam. NEET Biology is essentially an indispensable section as it is one of the most scoring subjects if you plan your preparation wisely.
