With all due respect, that is a kinda silly reason. Math and sciences ARE liberal arts disciplines. (Engineering is not, but then BC is starting up an Engineering program.)
Now, if you’d prefer not to have to fulfill BC’s Core requirements, ok. (But I would submit that some of those Core requirements will improve your critical thinking and writing skills, which is a plus for the MCAT and MD.)
That being said, NEU is a fine choice. But don’t discount a Jesuit education; they know how to do it right.
