Hello student

Yes generally all the NITs allow to change branch after the first year.

Change of branch shall be strictly in order of merit of the applicants. For this purpose the CGPA obtained at the end of the second semester shall be considered. In case of a tie, the JEE (Main) rank / SAT Subject Test Score  of the applicants will be considered. The change of branch is permitted only to vacancies as per eligibility and category of admission.
