There are two papers of Zoology for IFoS and CSE Mains Exam.
and Each Paper divide into two Sections.(Sections A and Section B)

There are Eight 8 Questions in each paper of Zoology, out of which Five 5 Questions to be attempted.

Sections A have 4 Questions.( Q1,Q2,Q3,Q4)
Sections B have 4 Questions.(Q5,Q6,Q7,Q8)

Question 1 and 5 are compulsory.

Out of the remaining Six 6 Questions, Three 3 are be attemped selecting at least one 1 question from each of the two sections(Sec A and B).
