Hello Renu Garg,This year for NEET 2020 form fill up was from 02/12/2019 to 06/01/2020. If some one makes a mistake in the application form then they can correct that mistake during correction Window time that was from 15/01/2020 to 31/01/2020. During this time if someone made mistake or want to make any changes in the form then he/she can do at this time.
On the request of people NEET again reopened the correction Window from 03/02/2020 to 09/02/2020. During this time also some one can make changes in the application form.But after that the information filled will be stated as correct. No one will be allowed to make any change.
So, you can't change your category at the time of Counselling as the seat given to you will as per your category.The only thing you can do is to mail to the neet exam authority about your mistake and they will allow than only you can change, but the chances are very less that they will allow to make change.
