Hi there,

It's depends on type of changes that you want to make in your neet UG counselling registration form. If you want to make changes in choice locking then you can make these changes but after submitting your choices. You can not make any change before 2nd round. You can make change only after 2nd round.

If you want to make any change in application form of NEET then you can't do that.

Hope it helps you

Good luck!
