Are you worried about the others just because the first response you got was a rejection? Or because you think there's a similarity between the types of candidates BC and BU typically accept? I always thought of those two schools as being pretty similar, in terms of academics and the types of students they accepted. But who knows?
I can sympathize with you... after my first response from a school (an acceptance) I felt great about my chances at the rest of my schools. After my fourth response (a wait list) I felt horrible about the remaining schools. Just remember there's not necessarily a correlation. Try and consider each application as its own entity, which it is.
Also, I'm curious about why you think Hastings is in the bag. Is it because your grandfather went to school there? I was always under the impression most schools (especially public ones) didn't give alumni connections much weight.
Again, though, I'm just some guy, not an expert on these matters.
