Hello akash,

Yes, you can change your category in neet application form during correction window. NTA provide correction period for the candidate. You can correct details like father's name, mother's name, category, etc. But you need to be ensure that the modify/edited details before submit during correction period. you can correct for one time only. The correction period starts from 15 January to 31 January 2020.

I hope this helpful for you.
