The National Eligibility and Entrance Test (NEET) is a competitive medical entrance exam held in India for admission to various undergraduate medical programs. The NEET exam is based on three subjects, out of which Biology has the highest weightage, accounting for half of the total marks. A strong understanding of the biology syllabus can help students prepare for the exam and improve their scores. The NEET 2024 Syllabus has recently been modified by the National Medical Commission (NMC), with a few items added and removed. In this article, we have provided the latest updates on the NEET Biology Syllabus 2024.
NEET Biology Exam Pattern 2024
In the NEET 2024 exam, candidates need to answer a total of 180 questions each carrying 4 marks. Out of these 180 questions, 90 questions will cover the Biology syllabus. The Biology section of NEET 2024 has two parts: Zoology and Botany. The questions and mark distribution of these two parts are given below.
