NEET Biology Question Papers

NEET Biology question papers serve as an important tool for preparation among aspirants. NEET Biology questions carry the highest weightage in the entire question paper; hence, Biology needs to be given special attention during NEET preparation. The NEET exam pattern consists of 180 questions from three sections, namely, Physics, Chemistry and Biology. The Biology section carries the highest weightage and is further divided into two sub-sections, Zoology and Botany. In this article of Shiksha, we bring the Biology NEET question papers of previous years for the aspirants so that they can improve their sectional preparation for Biology.

Biology forms the core of the NEET question paper. Hence, aspirants aiming to appear for the NEET should focus more on biology than on the other two sections.
