NEET 2022 is atleast a NEET exam away and so any information that we give will be speculative. And NEET 2021 will  be conducted with a reduced syllabus. While the syllabus has not been officially announced yet, it has been decided that the syllabus will be reduced by 30%;. Whether it will be online and held twice a year like JEE, we have to wait to hear from NTA which is the exam conducting authority. At this point in time, there is no official confirmation regarding NEET 2022. And regarding OBC, the Community you belong to should be listed in the Central OBC list for you to avail OBC benefits. Or else you will be considered under General Category.
