Hello Aspirant,

See if you have applied for BHMS under OBC reservation quota then you must be having OBC-NCL reservation certificate and if you don't have the certificate then your seat may be cancelled or you might be transferred to General quota which has no reservation. Usually the caste certificate is required at the time of reporting to verify the caste reservation eligibility but If you don't have your caste reservation certificate right now and you can get it within few days then you can talk to the college authorities and request some time and you can also give them an application with the copy of receipt which you got at the time of applying for OBC-NCL certificate. If they approve your request then try to submit your certificate within time but if they don't then ask them for an alternative.

I hope this information helps you.

Good Luck!!
