Hello Shruthi

According to NTA, the eligibility criteria for NEET 2020 for general students is that they get 50% in their Class 12th exams and for SC/ST students, they have minimum 40% marks in Class 12th. Now, you got 55% marks in your Class 12th examination, so you are eligible to give NEET 2020. As, only the total percentage matters, so your score in individual subjects not matters. Only, you have to pass all the subjects. So, don't worry because you are eligible to give NEET 2020.

Hope this helps and all the best for your exam.
