Chances at getting merit scholarships from American University?

<p>I would really like to go to American University in Washington D.C but it is VERY expensive. I have heard that Dean's and Presidential scholarships are given, but I am unsure of their approximate amounts and what caliber students get them. I have a 30 ACT, (11 Writing), 4.0/4.0 weighted 3.5/4.0 unweighted gpa, good leadership activities, and a good essay+recomendations. My parents make enough so I won't get any FAFSA aid, but they cannot pay even close for all of AU's cost. My question is this, how much merit aid could I expect to receive from American University? Thanks everyone!</p>
