Hello,

As per question i would say that the exam conducting authority will provide the application form correction facility only between the application form submission time period. 

If candidate have done mistake in the application form and wants to correct it, then the correction facility is provided by the authority.

 The corrections can be done in the fields such as name, qualifying exam details, address, contact, course for which applied, etc. However corrections has been provided only in some fields not in all. The corrections facility is provided only once. 

So read the details carefully and rectify whatever mistakes done. 

Good luck.
