Chordata | Zoology Optional | UPSC - CSE/IAS/IFoS | Exams Exclusive

These notes divided according to class taken by Dheeraj Sharma on Exams Exclusive.

Zoology is one of the optional subjects offered by the UPSC for the civil services mains exam. It is a reasonably popular optional subject among life sciences students who wish to pursue the IAS/IFoS exam. Zoology is the scientific study of animals, including animal anatomy, physiology, genetics, biochemistry, evolution, ecology, conservation and behaviour. It is an interesting subject and one that has great potential for the UPSC exam. However, it requires hard work and sincere answer writing practice out of students.
