I agree with ariesathena; she should take a Kaplan class, which I did (20 years ago). It was tremendously helpful, although the fact that I studied nonstop for months, using the class materials, was more helpful than the classes themselves.
I think that she’d be fine, even at BC or BU, though. Her undergrad school’s name on her resume and its alumni network will give her advantages that people at BC and BU who went to places such as Northeastern and Suffolk will not have.
