Zoology is a natural choice for UPSC aspirants with a life science background. It is considered a scoring subject due to its factual nature. Questions are generally straightforward and revolve around basic concepts, making it easier to score well if you have a good grasp of the subject matter. Figures and diagrams can be used to answer the questions. Zoology overlaps with various other disciplines such as ecology, environmental science etc. This interdisciplinary nature can provide a broader understanding of the natural world, which can be advantageous in the exam, especially in the general studies papers. Zoology is comparatively less competitive as the students usually from a science background choose it as an optional subject in UPSC.
