Knowing the NEET 2022 syllabus in advance will assist the students in their preparation for the examination.
The candidate must have Physics, Chemistry and Biology as mandatory subjects in their HSC (12th) and 11th to be eligible for NEET 2022. The biology syllabus has the highest weightage among all the subjects in NEET 2022. A student aiming to crack the NEET examination must know the Biology syllabus thoroughly. This article will discuss the NEET 2022 Biology syllabus, section-wise marks, weightage and more details.
Biology has the highest weightage in the NEET examination. It is crucial for students to understand the syllabus and prioritise their study plans to perform well in the exam. The NEET 2022 Biology syllabus consists of two sections: Botany and Zoology.
The Biology section in the NEET exam is crucial because it is the deciding factor in the final ranking. If more than one candidate gets the same overall marks, then the candidate with the highest marks in Biology will rank above the others. Before we dig into the NEET 2022 Biology syllabus, let us understand the NEET 2022 exam pattern:
