One such activity would involve filing various "change of address" notifications, for people / services who communicate with you through postal mail, addressed to the college postal address which you use.
Similar to postal mail, you probably have a college email address, issued to you when you registered as a student. Hopefully by now, you have setup a non college email account, and are busy filling out change of address "notifications" for the many services which communicate with you through email.
