Greetings, Rupa.

The education eligibility criteria for NEET unreserved candidates mention that  a minimum of 50% has to be obtained in the 10+2 examinations with Physics, Chemistry and Biology (PCB) as the major subjects.

I am sharing a link for further information on this as well as other criterias involved, hope it helps:
