Hello candidate,

As you have made a mistake in your category section while registering yourself for the neet examination it's better that you take the help of the correction facility window provided by the national testing agency where the candidates get a separate option to edit and re-enter their information and save it for the final time. as you already might have paid your registration fees for the examination it's better advise that you change your category at check other documentation and use the correction facility itself rather than going for or a new fresh registration and again paying the registration fees.

Hope you found it helpful!!
