Yes Kriya, you can change your college in TYBSc Chemistry but it depends on the rules of your university. Most universities allow migration/transfer, but you will need a No Objection Certificate (NOC) from your current college and approval from the new one. The syllabus of both colleges should also match, otherwise you may face difficulties. Also, it depends on seat availability in the new college. So, it’s better you confirm the procedure with your university and the college where you want to take admission.
