NTA hasnt announced syllabus for NEET per se. But based on the previous question papers, this summary has been reached. Biology is the biggest section in NEET, comprising about half of the exam, and acing this subject can help you in scoring more in the exam. NCERT is best book to study biology for NEET, and solving NCERT based questions will give an added advantage. Human Physiology and Genetics have maximum weightage in NEET. It is advisable to practise questions of Genetics from previous year question papers, which will give you a thorough understanding of how the questions are being asked. Topics of Plant and Animal kingdom have a lot of portion to memorize. You can prepare these topics by making a comparative table for the sub-topics and studying it together. Plant physiology is also equally important and easy to score.
