Dear Student,

You may be not eligible because for the eligibility of NEET 2021 you need to have physics,chemistry and biology as core subjects including English but you have done only biology from NIOS.You have to done NIOS with at least 3 subjects or say with 4 subjects including English to be eligible for neet 2021 as you can show your NIOS scorecard only if you have done all the required subjects from NIOS.You can confirm with NTA that if you are eligible by nios from biology and pcm with state board then what code you have to select in neet form

Thanks
