NEET Biology Syllabus 2024: Class and Topics-wise Syllabus in PDF

NEET Biology Syllabus 2024: NEET Biology Syllabus is a crucial aspect of NEET preparation. The syllabus has been designed to test the candidates’ knowledge and skills in Biology. Aspiring medical students must thoroughly understand the NEET Biology syllabus to excel in the NEET exam. NEET Biology syllabus 2024 will be based on the NCERT curriculum of Class 11 and 12. The syllabus includes both Botany and Zoology, divided into two sections, section A includes Botany, and Section B includes Zoology.

A comprehensive revision of the Class 11 Biology NCERT Book and 12 NCERT Biology textbooks is necessary because the NEET Biology syllabus is based on the principles covered in those texts. Throughout this article, you will get complete knowledge about the class, topic, chapter-wise NEET Botany and Zoology syllabus with the topper recommended book etc.
