High-weightage NEET Biology chapters in Botany and Zoology, the diagrams that fetch easy marks, and free chapter-wise practice for NEET 2026 aspirants in India.
Biology is half of NEET (360 marks) — your biggest scoring opportunity.
Highest weightage: Genetics & Evolution, Human Physiology, Cell Biology & Cell Division, Ecology, Plant Physiology, and Reproduction. Ecology and Human Physiology alone carry a huge share.
Diagrams to master: nephron, neuron, heart, digestive system, flower structure, DNA replication, and the cell. Label-based questions are common and easy if practised.
Method: NCERT Biology is king — read it line by line (NEET questions are often direct from NCERT lines). Make summary tables for classifications, and drill MCQs for recall.
Tip: revise diagrams and NCERT in-text + summary points repeatedly; that's where most marks hide.
