No chapter-wise weightage is given officially by AIIMS for Biology. Hence, aspirants must not depend on getting a fixed number of questions from each chapter. The chapter-wise preference can be made based on the syllabus, previous year papers, current trend of the paper, and importance of NCERT concepts.
Human Physiology, Cell Biology, Genetics, Molecular Biology, Reproduction, Human Health and Diseases, Plant Physiology and Ecology are a few of the chapters which need to be prioritised because these chapters cover a lot of concepts and questions can be framed from them.
The aspirants also need to keep in mind that the chapters marked as low priority must not be totally neglected because questions can be asked from various topics of the Class 11 & 12 Biology syllabus.

Weekly mixed-chapter test: After you have completed a few chapters, take a test consisting of questions from all the chapters. This will make you aware of your strong and weak points. Practising the AIIMS BSc Nursing Mock test is also helpful for time management.
Making notes with the help of charts and tables: Making notes with the help of charts & tables is beneficial for quick revision during the last few days of the exam.
A good score in Biology requires proper memory retention and understanding, along with proper selection of questions.
Revisit NCERT many times rather than reading it once.
Pay attention to high-importance chapters while not leaving other subjects completely.
Practice questions from each chapter and mixed MCQs.
Regularly solve questions from previous years.
Keep a mistake book.
