NEET 2022 Syllabus – Overview

The syllabus of NTA NEET is designed based on the syllabus of CBSE, ICSE, COBSE, and NIOS state boards of Classes 11 & 12. Therefore, students are not entirely new to the topics. Through the syllabus, NTA intends to familiarize students with the fundamental topics covered in NEET 2022.  

The Biology section of NEET constitutes a major part of the question paper. It has 360 marks allotted to the Botany and Zoology sub-sections, amounting to 50% of the total weightage of the NEET question paper. Hence, candidates must leave no room for mistakes here. Besides, the section is considered one of the scoring sections as compared to the other two subjects viz. Chemistry and Physics. So, anyone familiar with the syllabus and proficient in the basic concepts can score high marks in NEET 2022 Biology.
