Hello aspirant,
Since the dates of the university to fill the forms are gone therefore you cannot din the forms but there is an alternative which you can try.
First of all go and investigate about what can be done and let them know your problem. Iss you're problem is genuine then they might consider you.
Secondly there is also a second time form which needs to be filled so there are some universities that let students fill a second round of forms.
So please check with the university.
Or you may apply in other colleges if there is no option left
Hope it helps
