Hi Neha,

To be eligible for NEET exam you should must score 40% in 12th board in PCB as this is the bsic criteria to be eligible for NEET exam.40 % for OBC/SC/ST and 45% marks in PCB for general handicapped and 50% for General students.12th board marks will not be counted on giving you your NEET marks.The NEET rank will only be counted on the basis of marks obtained in NEET exam.

Hope this will help,please feel free to ask if you have any further queries.

Thank You.
