Yes, especially if you have roommates.
Who can I contact if I have any questions or don't understand  on what's included in the student aid offer?
Simply contact the financial aid office at the school. They re there to help ! It's important to understand what you're being offered e.g. , which items in the offer are grants and which are loans.
On a somewhat related note, I'm sure you're familiar with grants and student loans, so what can you tell me about them?
