If I may, let me weigh in a bit on this post.

First of all, the books he has listed are good ones, specially the critical bible. I don't think Kaplan math book is the best out there, but I won't knock it down completely either. But know that GMAT has revised its test format and added a new section; any preparation should include that section as well; so it is better to get a new comprehensive preparation material...unless yours includes that already.

Now about the score. 720 is a tough score, only you would know if that's true or not. But it takes a good dedication and time to prepare to get 720 and nobody will do that if they don't have intention of joining MBA..IMO.Maybe you just had free time in your hand or your are naturally gifted..I don't know.


Finally, about your blunt advice. I think you are right on certain degree, but understand there are different reasons people seek MBA. Some want to stay at their company and need MBA to increase their chance to go higher; for those people any kind of MBA, even online MBA, might help. For those wanting to gain knowledge of business/finance etc, MBA from other schools will help. But yeah, if you are strictly doing MBA to find a really good job (consulting in top firm or mgmt position in a new industry) then don't waste 2 years and hundreds of thousands of dollars in a run-of-the-mill school.
Edit: changed weight to weigh in the first sentence.
