Do be prepared for the eventuality that you will not get on-campus accommodation. This means you'll have to organise an off-campus place, furniture and other essentials.
There are plenty of student places around town that are already furnished, but most don't include the bedroom stuff (desk, bed etc.).
And if you don't get an on-campus place, I would quickly organise off-campus stuff, because you won't get anything decent during O-Week, by then it will be too late and you'll end up with the scraps.
Also remember that if you have to go off-campus, you'll likely have to pay a bond, plus two weeks in advance. This is Real Estate standard practice. This means (for example) if you're sharing with 3 other people, and if the rent is $250.00 per week, your share of the bond will be $333.33, as well as having to pay two weeks advance which would be $166.66, the total payment being $499.99.....
And you have not even thought about furniture, utility connections (phone, internet, electricity, gas).
And people who have only lived on-campus wonder why those living off-campus are anti-social for the first few weeks.... Its because we have no money.
