Biology is 50% of the NEET paper (360 of 720 marks), so it decides your rank. Here are the highest-weightage areas to prioritise.
Class 11 high-weightage: Plant & Animal Kingdom (classification), Cell Structure, Plant & Human Physiology, Biomolecules. These carry a large, predictable share of questions.
Class 12 high-weightage: Genetics & Evolution, Biotechnology, Human Reproduction & Reproductive Health, Ecology. Ecology alone is one of the most question-dense units in all of NEET.
Strategy: Master NCERT line-by-line for these units first, memorise every diagram and example, then drill MCQs to lock in recall speed. Most NEET Biology questions reward fast, accurate memory of NCERT facts.
