| II | Genetics and Evolution | Heredity and variation; Molecular Basis of Inheritance; Evolution | 18 |
| III | Biology and Human Welfare | Human Health and Diseases; Microbes in Human Welfare;
Strategies for Enhancement in Food Production |
14 |
| IV | Biotechnology | Principles and processes; Biotechnology and its Application | 10 |
| V | Ecology and Environment | Organisms and Populations; Biodiversity and its Conservation; Ecosystem; | 14 |
| Total | 70 |
2. Invest in study material
Buy reference books for class 12th Biology along with reference papers, previous year question papers, question banks and sample question papers. Listed below is a list of study material that you can refer to for your class 12th Biology exam:
- NCERT books for class 12 Biology in Hindi or English
- CBSE Biology chapter-wise solved papers class 12th – Arihant Expert
- Pradeep’s A Text Book of Biology class 12 – P.S. Dhami
