Hey,

This is something you must have been active about if you were to desperate to take admission in the respective college. But now what's done is done.

I can advice you to talk to the authorities regarding your problem and tell them a legit excuse in order to make yourself real from your end. They will surely help you if they have seats left to fill in the respective course.

This is the best you can do at this time because the deadline is passed and it will be only possible if they allow you to fill the form again.

Hope that helps.

Thank you.
