Apply Concepts to Real Life Scenarios: To understand Biology better and build a deep understanding, relate topics to everyday examples.  For example, while studying immunity, draw parallels with how vaccines protect against diseases like COVID-19. When learning about the nitrogen cycle, relate it to how farmers use fertilizers to improve crop yield etc.

Write well-structured answers: Answers that are well structured fetch higher marks. Give answers point-wise, using sub-headings, flowcharts & bullet points. If a question on Mendelian inheritance appears, start with a brief introduction, illustrate a Punnett square for clarity, and then summarize the findings. Use keywords from the NCERT books, such as dominant and recessive traits, to demonstrate a thorough understanding. 

Practice, practice, practice: Practicing concepts and diagrams will ensure that you score beautiful marks in the CBSE 12th Biology exam 2026. Use mnemonic techniques to store information easily.
