NDA Biology Notes – Chapter-wise Topics, Maps & PYQs

NDA Biology Syllabus and Preparation Strategy

Biology is an important part of the General Ability Test in the NDA exam. It contributes about 15-20 questions from subjects that include human biology as well as other areas. Candidates may refer to the NDA Syllabus to know more about the topics of this subject before starting preparation for the chapters. Topics of this subject are Human Biology, Plant Biology, Genetics and Molecular Biology, Animal Biology and Ecology. Each of these topics poses its own level of difficulty and has a specific approach to preparation.

Chapters like Circulatory System, Digestive System, Nervous System and Endocrine System from Human Biology carry good weightage in NDA examinations. Notice that understanding is more important than just identifying the terms in these chapters. Genetics, Evolution and Ecology are also common topics in NDA Biology. Candidates are advised to check previous years’ question papers in order to know the commonly asked topics.
