What schools give good aid to National Merit Scholars?

I will second @RedbirdDad ; my S14 is about to graduate from Barrett at ASU. He has had a great experience. He will graduate with a BS in Chemistry with a minor in Business. He received over 30 AP credits that helped him graduate in 4 years even though he changed majors a few times. If you make NMF, they offer 100% tuition. You will need to cover room and board, less than $15,000 per year. Depending on your EFC, you might even get more help. It is a great school, especially Barrett. Barrett provides a smaller, elite college experience on a larger campus. They have turned out a good number of Rhodes, Fulbright, Eisenhower, Marshall and Udall Scholars every year. Check out Barrett, The Honors College.
