    AIIMS BSc Nursing Biology Chapter-wise Weightage

    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.
