Phantomcow - there IS the matter of Cost of Attendance (COA) - sometimes, an increase in some types of gift aid necessitate a decrease in other types of aid, UNTIL the FA Office can process through adjustments to the actual need analysis - which tells the school how much the family should be able to contribute towards the cost.
The formula is: Cost of attendance minus Family contribution = NEED. The cost of attendance is actual and estimated costs - actual college tuition and fees, room & board, etc., plus estimated amounts for books, travel, entertainment, etc. A college can make adjustments to its COA whenever they WANT TO (non-federal aid is limited and therefore rationed! When they give it out, it's gone!) The Family Contribution calculation is set by Congress - all a school can do is tinker with the formula components. For instance, a school can chose to update a particular student's family income from the base year (2008) to current year (2009) if, say, a parent has lost their job. They can choose to offset income for natural disasters or major medical expenses. Any tinkering like that can only be done on a case by case basis, and requires that the school re-process the student's aid application through the Federal Govt. - Changes made this way apply ONLY to the school that made them, and a school is NOT required to make any changes. Aside from that, some scholarships are considered not to be interchangeable - sometimes a student's qualification for one scholarship negates his or her eligibility to receive a different scholarship. Sometimes, academic tuition waivers or scholarships cannot replicate state grants for aid - it's a complex mix, and I would suggest that you wait for your final award before you request an appointment to figure out what the story is.....
