Can one cancell his govt BPT admition after first year if he got mbbs seat next year through neet 2020

Hey Furqan,
Yes, ofcourse you can but you have to check the rules and regulations of the college (from which you are going to do Physiotherapy) as there can be requirement of paying bond money for retrieving your original documents from the college.
If that is done, you are free to join any college for MBBS course if you qualify NEET 2020.
You are also required to submit a gap letter for the time period you have spent for preparation after your 12th grade till joining the medical college.
Good Luck!

Dear Furqn, instead of cancelling a seat, you have to request for a TC and then take admission in the MBBS college. For this you will have to talk to the administration of the college you have joined BPT in. Most students take a TC and it us quite an easy process. So just to answer your question, if you get a seat in NEET in 2020 you can take a TC from BPT and join MBBS
