Zoology Is The Best Optional For UPSC Because :
Questions Are Straight Forward: Questions are directly picked from the syllabus so you do not have to think about the central idea or theme of a question in exam like what happens in some optionals for eg. pub ad, pol sc, etc. Just look at the question and start writing!!!
Figures And Diagrams: This is the best part as it fetches more marks as compared to writing. Also when you have less time in exam (happens most of time) and more questions to answer drawing a diagram takes less time and fetches more marks as compared to writing in words.
Marks Assured: In this along with other optionals like botany one can be assured of marks and predict it if all or most of the points with neat and labelled diagram is drawn.
