About Class 12 Biology for JEE & NEET
Biology is the highest-weightage subject in NEET, accounting for 90 out of 200 questions (Botany 45 + Zoology 45). It covers Cell Biology, Genetics, Plant Physiology, Human Physiology, Ecology, and Evolution. Unlike Physics and Chemistry, Biology rewards thorough reading and recall — every NCERT line is a potential NEET question.
Key Topics
- Cell Biology & Cell Division
- Genetics & Molecular Biology
- Human Physiology
- Plant Physiology & Photosynthesis
- Ecology & Environment
Exam Tip
NEET Biology has the highest scoring potential. Focus on Human Physiology and Genetics (highest weightage chapters). Diagram-based questions (mitosis, photosynthesis, heart) appear every year. Class 12 Biology (Genetics, Reproduction, Ecology) contributes more questions than Class 11.
How to Use This Question Bank
Use the subtopic filter to practise diagram-based MCQs separately from definition-based ones. Switch to Hindi to match how many students study NCERT. All questions include the correct answer with a step-by-step explanation.
