Exam form

YES. There will be a correction window after sometime. You can make corrections to your application at that time.

I am not sure about the time when it comes bcoz I never required to use it. But, I know that there is a correction window when u can make changes in your application without any fine. And, later on after a time limit you get a Paid correction window also, when you can make changes after paying fine.

If you try to check the website on which you filled the exam form, then, you may get some information.
