can i change my university after studying in another university for an year ??

Yes you can change but you need to take migration certificate from the University where you study. If they have course they will admit you.

Dear shekar, Yes, As correctly said Mohsinkhan sir, The process is called "MIGRATION" You need to ensure whether your university permits migration. If it permits you need to get required documents like, Migration certificate, T.C etc In case of any doubts feel free to reply, Wish you best, Arun.
