Congratulations to son on his great achievments and scholarships.
One thing mentioned here is concerning financial aid.
Any scholarships earned are applied to tuition/school costs first, then if there is a balance and "aid" in the form of grants, assistance, etc. was offered then it will be used.
If the total amount of scholarships earned is more than the total costs, then your son will recieve a refund to his "college account". Usually an account is set up through the school for funds to be applied and deducted as needed. If there are extra funds your son will be able to use those for living expenses.
My son recieved a full package of financial aid and then recieved a very nice scholarship for 4 yrs. The school applied the scholarship to his account and then took any aid out "the back door" so that all numbers basically stayed the same but the sources of the funds where different.
When DS won the scholarship I was so happy that he could then purchase a computer, new shoes, living supplies for dorm (sheets, etc) and the cost of marching band. I was kinda sad to learn that this money was applied directly to costs and he would then lose that amount in aid.....basically a wash.
After all his hard work and achievements, in reality the scholarship did not help his situation.
You or your son can call the financial dept of the school to see if they have a specific way of handling this issue. Y'all are not the first to have this happen so I am pretty confident that they have a procedure in place.
