Hello sir,

I hope you are aware of the fact there is no upper age limit to appear in NEET . So there is no problem with age factor here . While as you said you obtained 55% in 12th boards . So dear sir if you are from general category you should have a aggregate percentage of 50% in PCB subject while 40% for SC/ST . I hope you have studied biology as it is compulsory to have biology as a subject in 12th only then you can appear in NEET. I hope the information provided by me is helpful to you.

For any more for the queries feel free to ask again.

Best wishes
