THe Baruch MS programs are more lenient on admissions requirements than their MBA program is, because the stats for these programs are not figured into rankings. Your GMAT is well within their 80% range, which is roughly 510-700. As for experience, there the requirement is also loose and you will get much better consideration in the MS programs than you would in the MBA without post undergrad experience. If you can articulate well why now is the best time for you to go back to school, you should give it a try--you might be surprised how easily you get in!
