Hello dear student ,

As you said you are done with your 12th board exams but you also want to prepare give Neet exam. and I know you are aware of this fact that you need to have biology as your subject in your class 12th to be eligible to appear in neet while this is the first criteria. if you want to appear in NEET you can appear for Neet in the next coming year meanwhile after the results are out and everything settles you can take admission in national board of open School which is recognised by government of India and those people who to take admission in this open University eligible for every kind of exams conducted by government or private. so don't worry that will not be a problem and it will be considered it's just that you need to have a valid , authenticated or rather say recognised board. also you need to have physics chemistry biology as your subjects particularly and if you belong from general category then the minimum marks required by you in all these three subjects are 50% while if you belong from SC ST OBC category then the minimum marks required by you is 40% which is an aggregate percentage in all of these three subjects. I hope this helps was helpful

Thank you
