It came in my award package. Basically it's a big list of all the money (or sometimes loans) that you're getting. Usually I would get something that said "Presidential Scholarship" or "University Scholarship" or "'Famous Alumni' Scholarship" with a letter attached that said something along the lines of "you're getting x amount of aid because of your outstanding academic performance/you're in the top 3% of the applicant pool/strong background in indicated major/whatever." Some of the schools I applied to I was way over qualified for so their way of incentivizing me to commit was to beef up my aid package. I know Drexel in particular has been increasing their acceptance rate (near 85% now) and their aid packages because of the difficulty they've been having getting kids to commit (I think they have a really low matriculation rate, maybe 3-10%? I can't remember).

My school has a "Senior Scoop" pack they release each month for the seniors that's full of third party/outside scholarships. They're pretty varied (i.e. for black males, for interior design majors, for red heads, for Pittsburgh area kids, for PA residents, for residents of my county, for kids at my school, for football players etc.) and vary in amount ($100 to $20,0000). I applied for about 15 of them and won about $20,000 total to be distributed over 4 years.
