As a BU/BC student, I can honestly say Biglaw, if that's what you want, isn't out of the picture by any means.
First off, while the schools curve at a 3.3 in theory, the actual medium is a bit below, so you should be right around the middle of your class (perhaps a hair below).
Second, I know several people with significantly lower GPAs than that working at large law firms in Boston, NYC and DC. As the other posters have already stated, you'll just have to work harder (likely resorting to waves of mass mailings as the fall term goes on), interview better and, ideally, have an angle of some sort (ie demonstrable interest in a particular legal speciality, geographic ties, URM status, etc) to get in, but it's definitely possible.
One or the other, not both obviously. I attend either BC or BU.
So what's my strategy folks??
