Quick Summary: The NEET Biology syllabus 2026 is likely to remain the same as that of 2025, as no official update has been released by the National Testing Agency (NTA). It has chapters from both Class 11 and Class 12, from both Zoology and Botany. The syllabus is segmented into ten large units that represent different areas of biological science. It includes chapters on Diversity in the Living World to Ecology, and Environment. In this blog, we have shared the important chapters, chapter-wise weightage, preparation tips, and much more.
The NEET biology syllabus 2026 has been released by the NMC on their official website, nmc.org.in. Biology is the most important and one of the most scoring sections in the NEET. The biology syllabus for NEET 2026 is vast and includes everything from ecology to cell biology, which also carries 50% weightage of the exam. The biology NEET syllabus for the 2026 exam is prepared from both Class 11 and Class 12, and includes chapters from Zoology and Botany.
NEET Biology Syllabus and Paper Pattern 2026
The Biology syllabus of NEET consists of two sub-sections -Botany and Zoology. Based on these subjects, NTA prepares MCQs (multiple choice questions) based on four options (only one correct). The NEET Biology Syllabus 2026 is based on the pre-COVID format. Students will have to solve 90 MCQs (for biology only), with 45 questions in each section and a total of 360 marks. Each right answer awards 4 marks, while 1 mark is deducted for each incorrect answer. The total time (race against time phrase meaning) given for the paper is 3 hours or 180 minutes.
The Biology syllabus for NEET 2026 includes 10 major units and nearly 20 subtopics under those. Students can score high if they can prepare the NEET Biology syllabus with a clear comprehension. It includes both class 11 and class 12 chapters in almost equal proportion, and hence, you must study the complete biology NEET Syllabus.
