NEET Biology Syllabus 2024
NEET Biology Syllabus 2024: NEET, the National Eligibility cum Entrance Test, is a competitive medical entrance exam conducted in India for a career in medicine. Since biology is the highest-scoring subject in NEET, the subject dominates, with almost half the number of questions being asked in biology alone. The National Medical Commission (NMC) recently released the NEET 2024 syllabus on its official website, nmc.org.in. The NEET 2024 syllabus pdf by NTA is available here.
The questions asked in the Biology section of the NTA NEET are generally concept-based and straightforward. Hence, well-prepared students can score higher marks. Students need to be well acquainted with the latest Biology NEET syllabus 2024 and exam pattern. Knowing the NEET 2024 biology syllabus will help students understand the chapter-wise topics to prepare for NEET 2024. Also, it is essential to know the marks’ weightage.
