Just thought that I'd chime in that in looking for non-school-afilliated scholarships,
Fastweb was of great help (unlike my school's guidance dept), pointing me to everything from local service club scholarships to Northrop Grumman and UTC scholarships (and, of course, my new favorite, the
apple student scholars program). The site takes some basic data on you to filter the scholarship list (by location and/or intended academic field) and then gives you a list, sortable by deadline date of all applicable scholarships in the database.
