Since you have not mentioned the college name i don't know what would be the policies of this college. But usually if you are at a shortage of attendance the college authorities ask to pay fine to let you sit in the examination. Look if there's as such any option.

The second thing you can do is write a formal appeal to the college authorities and apologize them. Tell them your reasons due to which you were unable to attend classes, also give them a medical proof if you have any.

If still the college doesn't allows you seek legal advice.

Also keep checking if there are supplementary exams and try to give them. So that you don't waste your one year.
