Hey yes the exam you need for MBBS is NEET 

you should have  your 12th & 10th certificate & 12th should be done with 50% or more in board exams (PCB) . That sets the eligibility criteria for appearing for NEET examination. 

Hope that helps

Hello

The only way is to give NEET exam. The eligibility criteria is your 50% aggregate result in PCB - 12th. It doesn't matter that if you're pursuing BPT. So by giving NEET you can apply for MBBS.
