Looks like most of these scholarships are extremely competitive or very specific, for example,Children of active tobacco growers who live in the Southside area of Virginia.
They are highly competitive, but they’ve increased the number of them over the last year or so. Aside from the donor scholarships which are very specific (and I’d expect fewer applicants for them, if you qualify), the individual colleges offer better opportunities, and many don’t require a separate application. E.g, the Pamplin business school awards merit scholarships to approx. 10% of all freshman, the Davenport and Pratt are decent engineering school scholarships, and there are 5 Honors College scholarships based on merit. But it would sure be helpful to not have to dig for information on where to look and how to apply, or to have different application standards depending on the college you are interested in.
