That depends on your goals. Want to go work for “big law” and make fat stacks? Then prestige is what you need and hope that the debt thing will work out. Are you looking to do public service work or working in any other area of law that will provide a good-but-not-insane paycheck? Then choosing the best school that you consider affordable is the right choice. Note that low-average or poor quality schools might offer you full scholarships: that’s still a bad idea.
Boosting up GPA is hard, but I’m sure you can do this. Take advantage of all the help on offer: CFLC (tutoring & academic coaching: bit.ly/connors), meet with all of your professors, create study groups with other students, find productive places to study in BC Libraries, work with librarians on all of your research papers (library.bc.edu/ask-a-librarian), and then study like mad for the LSAT’s. You’ve got this!
Why not schedule an appointment with the Career Center (and they also have drop-in sessions for pre-law students) – they’re experts at this. Here’s their page with details and signup links: http://bit.ly/bcCareerCtrLaw
