Hey Bhavana.

According to the eligibility criteria laid out for NEET 2019 you need to pass class 12th boards exams from a recognised board to be eligible. Along with this you also need to score a minimum aggregate of atleast 50% marks in Physics, Chemistry and Biology subjects together to be eligible if you belong to the Unreserved category. So if your aggregate percentage in P+C+B is less than 50% you are not eligible. As Your aggregate in PCB is less than 50% you are NOT eligible.

Best of luck
