Hi there,

Although you have not mentioned the form name but this generally applies to all the forms related to competitive exams that after the submission deadline is over you are provided a time period called 'correction window' in which you can make correction to your form. You'll be notified about this on your registered email id. They do not particularly tell you what changes needs to be done but may mention the points that you need to look up and what all the things that you can't edit. So while checking your form you can find mistakes and correct them.
