Hello,

To be eligible for NEET candidate must have passed in 10+2 with Biology, Physics, Chemistry and English from a recognized board. Candidates belonging to general category must have passed with minimum 50% marks in PCB, for SC/ST/OBC it is 40% marks and for PWD it is 45% marks.

Your percentage in PCB is 39% which makes you ineligible. You can appear in NEET but your marks must increase and you must obtain the result before counselling. As of now NEET counselling dates are not yet announced. If your haven't scored the required marks then you are eligible to get admission even if you qualify in NEET.
