I do think that Wesleyan should remain a contender as it has an African Scholars Program that covers the full cost of attendance for up to 10 African students each year. The link on this page for the African Scholars Program goes to the Freeman Asian Scholars Program, but I suspect if you reach out to Wesleyan, you can get access to the correct information:
