JD/MBA - Is a 690 Good Enough for Columbia?

Hi All,

This is my first visit to the site, and I have to say I'm really impressed with how helpful and knowledgeable you all seem! I've been thinking about business school and I would appreciate a little bit of advice if you have time.

I am a law student at Columbia University, so if I get an MBA it will be through a joint program with the business school. I have been looking at the GMAT a little bit using a Kaplan GMAT book, and tonight I took the included hard copy practice exam and scored a 690. I saw that the range for CBS is about 660-760, with an average between 700 and 710. I know that for law school every LSAT point counts, and if you are even one point (which usually translates to literally one LSAT question wrong) below a school's median it significantly changes your odds of admission. Are business schools as hard edged about numbers as law schools, or is it more acceptable to just be "in the neighborhood" of the median? If a 690 isn't good enough, how much do I need to improve to be competitive? Are there any study materials that you recommend?

Also, I've heard rumors that standards are a bit different for joint degree applicants at a lot of schools. For example, they might overlook less work experience from law students as they tend to be younger than the average MBA candidate. Does anyone know if this is true?

I'm sorry for all the questions, but I am really new to this. Thanks in advance!
