Hi

Yes, you can leave your BHMS course and can give Neet examination

This is because,
There is no rule which says that if you are doing bhms  or any graduation or leave it in between you become ineligible for Neet examination, as to be eligible for neet what all one needs is :

* to must have passed 12th board examination with physics, chemistry ,biology/biotechnology and English and must have got:-

-) at least  50  % in aggregate of PCB  i.e Physics, Chemistry and Biology/Biotechnology  in 12th examination  if belongs to general category

-) at least  40%  in aggregate of PCB if belongs to  Obc/ Sc /st category

-)at least 45 % in aggregate of PCB in case of general/ews pwd candidates to be eligible.

So , you are definitely eligible for Neet 2021 examination ,even if you leave bhms in between and after qualifying Neet examination you can get admission in medical colleges for MBBS etc on the basis of rank or marks obtained by you in NEET

But yes,
You need to check your college Bond once which was signed by you during the admission because you may need to pay penalty amount for leaving the BHMS seat without the completion of course.

For example,
In North Eastern Institute of Ayurveda and Homoeopathy-Ayurveda Shilong as per their bond  , if you leave the BHMS seat within one month of admission then you have to pay penalty of 50,000 rupees but if you leave any time after one month of admission then to pay penalty of 3 lakh rupees
