Think ROI.
For most people doing ok in their careers, anything less that a Top 20 MBA is not worth it. You’ll want access to a top notch network, recruiters, and will be able to really enjoy the 2 year experience.
Sure you can go to a lesser ranked school and still land a solid position, the chances are working against your favor. Also, a few things to think about: What kind of economy you will be graduating into? That can have a significant impact with regard to your lifetime earnings.
