As you have asked about the M.Tech streams other than computers after
B.Tech check below for the information

Admission to some of the branches needs legal GATE score in the same
department that one wants to change.

For example, if someone wants to change for Electrical Engineering to
Computer Science in M.Tech, he needs to have a valid GATE score in
Computer and IT stream.



The details of the eligibility in different departments with additional
requirements are given below.
