Hello.
You didn't mention that which course you are doing so I am considering it BTech. So for b tech you can change your college after completion of your first year but if you are expecting to change your college in second semester so it is not possible after the completion of your second semester that is your first year you can take lateral entry direct in second year in another college by having the NOC of your college and the NOC of the other college for that you will have to fulfill the eligibility criteria in which you are going to take admission basically they put their eligibility criteria to have dicided percentage in your first year.
Best of luck.
