NEET Biology Class 11 Notes Syllabus 2026-27 (Revised): Chapterwise Syllabus, Weightage, Deleted Topics
NEET Biology Class 11 Syllabus 2026-27 includes 10 units. This year some chapters like s-Block, Hydrogen, States of matter, and Environmental Biology have been removed from NEET Biology Class 11 syllabus.
After the release of the revised Biology syllabus by the National Medical Commission (NMC), you have to prepare fewer chapters for NEET 2026-27. Animal Kingdom, Morphology of Flowering Plants, Some basic concepts of organic Biology, and Anatomy of Flowering Plants are some high-weightage chapters from the class 11 Biology syllabus for NEET.
NEET exam pattern has been revised this year. To prepare your best, you must have the best study material for Biology syllabus. Along with that, you must solve NEET Biology mock tests and previous year's papers regularly.
