BC is a really finicky, hard to predict school. While it is certainly frustrated to get rejected, I wouldn't take it as any indication of things to come. Taking a look at LSN for this year or years past shows that BC is usually all over the place. I have friends with 170+ and decent GPAs that were rejected by BC. They really are just a crapshoot.
I think BC is heavily into soft factors this cycle. I've found several people who got in who have both lower GPAs and LSATs than me, but most of them are varsity athletes, non-traditionals, or spent time in the military.
