The Award Overview in Trailhead lists student cost of attendance.  This includes full-time tuition (unless the student is graduating in December), room and board for housing either on-campus, off-campus, or with a parent, books, transportation, and personal expenses.  THIS IS NOT YOUR BILL.  Students are charged for the credits they take and living on-campus.  All other components are used for financial aid budgeting to allow families to borrow more than their tuition bill to pay for other living arrangements and books.
