I know at least a couple of people there are 2nd year students.
One of them is transferred student. Basically I think 2nd degree student
is treated almost the same as other student, i.e., you don't have to be with Woodsworth college as transferred or visiting student.

Can you apply for student ID now? The library number is on it. I remember you can do it before school starts.
Or you can send inquiry to housing office to ask them for help.
