Regardless of where you spend your first semester – halls, student housing, or at home – you’ll be surprised how much time you spend in your own room. School is an all-day affair; at university, the days are more fractured, so the onus to study (or whatever you came to university to do) is on you.
Expect a lot of down time in your room. Your bedroom is your sanctuary, but unless you’re in shared housing or staying at home, it’s also your only personal space, so treat it like a mini home.
