Unless you go to a top 10 school, go in the evening part-time. You’re then running the clock on job experience AND getting an MBA, and when it comes to job hunting time employers like an MBA but they like an MBA with experience even more. Also, unless you work in the public sector and just need a degree from an “accredited” school for promotion avoid non-ranked schools as well as online schools, they’re just going to waste your money by not returning you the salary to make the expense worthwhile.
Unless you’re a career student or are unemployed, make it an executive MBA. Pay as you go, as much as possible, get your books used at one of many websites, sell said books back to pay or offset the next semesters books and you can get out with student loans of less than $30,000.
