Hello,

If your last day of  the cancelling date is passed then  it might have a problem you cancelled it now but some amount of money you may pay for registration or fee they asked for that may have not repaid it depends on the term and condition or policy So be ready for it.

You can cancel it visit the official website. You can check with the college you have self reported to. Tell them your issue, it depends on terms and condition of that college.

Hope you understand.
