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?
Your school will give you your grant or loan money in at least two payments called disbursements. In most cases, your school must give you your grant or loan money at least once per term semester, trimester, or quarter.
