General Note:

The Senate of the Institute has approved that Ph.D. qualifying examination will be conducted in two areas from the list of qualifying examination areas of each department. Each student will choose two subareas; one of these must be the sub-discipline in which he/she proposes to undertake research after the consultation with his/her notional supervisor.
 
As per requirement, each subarea may have several sections with a total of 150/160 marks for theory and 50/40 marks for viva. The duration of each theory examination will be 3.0-4.0 hrs. Viva may be conducted separately for each sub area. A student will get a maximum of two attempts for clearing the qualifying examination (Ref clause 8.05-8.11 of academic regulation).
 

Course content of each area is given below.
