That combined with the experience you get as an officer in the Marine Corps will get you a better offer than a Wharton graduate.
The Marine Corps experience might get you that cup off coffee your first day on the job!:icon_wink Better than Wharton undergrad or MBA? I think the Wharton MBA will still trump the Marine experience.
I'm doing the Boston University MSBA program. I have 1 1/2 semesters left. It's a weekend program, which fits better than the weeknight programs that the other extension programs had. The professors have generally been very good, but if you had a strong undergrad business background the 1st halves of many of the courses tend to be a bit repetitive. Overall I've been happy with it. Even the support staff is extremely helpful there.
