Dear Trinath, once the last date for filling in the applications has been closed, NBE will open the correction window. You will be notified about the errors or discrepancies from your application form. This will be approximately within 15 days after closing the registrations. From thereon, a weeks time is given to make corrections to your NEET PG application form. Please check if the Edit Profile option can be used. If you can use it, go ahead and make the changes. If thats not an option I would suggest you wait for the correction window to open. Hope this helps!
