hi,

to get admission in ms 2 years duration course of iiit hyderabad , you need to appear in pgee exam conducts by iiit hyderabad exam authority. syllabus for the test is , you need to choose any of the disciplines between cse or ece or mathematics, however if you have prepared for gate exam and have good grip on the core subjects of ece then you should take ece, see the mathematics questions level will be higher than engineering mathematics since msc passed candidates are also eligible to participate in pgee exam.

hope you may understand.
