Hi

As of now students with biology as an additional subject are eligible for neet so going by this. Yes,  you would be eligible for NEET 2022  if you studied Biology as an additional /optional subject from  NIOS which is again a recognised board and also would be  eligible for counselling

This is because,

The eligibility of students with Biology as an additional / optional subject  is in the supreme court but until it gives its judgement students, these students are eligible for neet

Here's the eligibility criteria for NEET :-

-----------) Qualification required :-As per Neet eligibility to be eligible you must be either appearing for 12th board examination  or should have passed 12th board examination with physics, chemistry ,biology/biotechnology and English as core subject.

† ††Important Note :- Students who have passed Biology as an additional subject are also provisionally eligible for neet until Supreme Court gives its judgement.   For neet 2022 there's still time left so in meanwhile if judgement comes then eligibility of biology additional students will depend upon the outcome of judgement.

-----------)  Percentage required :- You must get

• at least 50 % in aggregate of PCB i.e Physics, Chemistry and Biology/Biotechnology in 12th examination if belongs to general category

• at least 40% in aggregate of PCB if belongs to st/Obc/ Sc

• at least 45 % in aggregate of PCB in case of pwd candidates to be eligible.

-----------)  Age limit :-

• Lower age limit:- to be eligible for neet  one has to be at least 17 years old or more by 31st December in the year of appearing for the examination .

• Upper age limit :-The upper age limit  is 25 years as on the date of neet examination and there's relaxation of 5 years for obc ncl/SC/ST /PwBD students means upper age limit is 30 years for these categories.

†††† But since 2018, the case of upper age limit is pending in supreme court , and so there's no upper age limit as of now until supreme court gives its judgement over it.
