Yed u can change. Bt it also depends on college if the seats are full for particular branch then it is not possible. If seats are vacant then u can change ur branch and u have to get more than 8.5 SGPA per semester

Dear Riya

As per my experience, if you'll get branch topper you'll have the chance to change the branch but it changes from college to college. Some college won't allow all these.

Please do care of that.

All the best.
