UMD College Park has a by-invitation honors college that appears to include a merit scholarship. I am a big fan of honors colleges for several reasons. FIrst, they foster a closer sense of community, and at some schools have their own dorms. Second, honors college students get first dibs at class registration, which can be very helpful in programs where pre-reqs fill quickly. Third, honors students are tracked into classes that are taught at a higher level then the corresponding classes for the general student population, and these classes are likely smaller. Fourth, honors students generally get more face-time with professors and research opportunities than general students. And fifth, many honors programs include generous merit awards.
I encourage you to research honors programs at College Park and any other schools you are thinking of adding to your list.
