Ah, then it all makes sense. Say, what if I have any questions or don't understand what's in the aid offer?
Then you should 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.
What if the school simply doesn't list the cost of attendance on the aid offer?
In that case ask the financial aid office for this figure. Make sure it includes amounts you will pay to the school directly such as tuition and fees as well as other costs such as living expenses, books and supplies, and transportation.
