3. Master Diagrams and Labeling Biology involves many important diagrams, such as the human circulatory system, plant structure, and molecular structures. Practice drawing and labeling these diagrams regularly. A well-drawn diagram with correct labels can fetch you easy marks in the exam.

4. Revise NCERT Textbook Thoroughly The NCERT textbook is the most important reference for CBSE Class 12 Biology preparation. Read each chapter carefully, and make sure you understand the concepts in detail. The exam questions are mostly based on NCERT, so avoid relying on additional reference books unless necessary.
