Zoology as an optional paper was good and experience was very much perfect. As I felt difficult to appear and clear but joining the coaching institute helped me lot in clearing the techniques and improving my skills. Chanakya IAS Academy provided me lots of guidance to appear in this exam. If you take this subject as an optional, you should ideally be a graduate in Zoology, Medicine, Pharmacy, Dental,etc. If you had any of these subjects,then you can have the aptitude to command Zoology as an optional.
