Joint JD/MBA?

Most, if not all, national universities allow applicants to apply for the joint JD/MBA after matriculating into either the business or law school. You must submit your materials by the fall or winter deadline however, which could be a very nerveracking process.

Essentially, about half of the LSAT and GMAT overlap, so you would do yourself a tremendous favor by studying LSAT CRs RCs and logical puzzles while you tackle GMAT math and SCs. I would think that many of your LORs and essays might be able to dovetail as well.

As dukes points out, Northwestern is probably one of the only recognized schools that accepts the GMAT only. Keep in mind that the competition is incredibly fierce strictly because of that laxed requirement. Offhand, I recall something like 10% of all applicants are offered a seat- roughly the same chances a Stanford applicant faces.

Another not quite as tooth and nail accelerated three year JD/MBA to consider is Kelley.
