Yes, like most other IITs and NITs it is possible to change your branch at NIT Manipur. My brother joined civil engineering at the institute but changed to CSE in the 2nd year, so I can tell you the exact process.

• First, your CGPA after 1st year must be among the top two in your branch.
• You should also not have any active backlog in the first year.
• If there is a clash between the CGPA then the JEE MAIN ranks of the students are taken for the tiebreaker.

NIT Manipur offers the branch change option only to two students at the maximum.
