To be honest, I found "the material" irrelevant, mostly. There's vast swathes of papers written about obscure and tiny parts of the overall subject. Any given paper is probably correct, but covering such a tiny part of the subject that spending the time reading all of them is inefficient (if not impossible).

Also, given that the subject in question is "business", and the practice of business was being changed (as it is again now) by the application of new technology, so a lot of what I was reading was only borderline applicable any more.

MBAs are weird. To qualify to do one you need to have years of practical experience managing in actual business. But then all of that knowledge and experience is disregarded, and you're expected to defer to papers written by people who have only ever worked in academia and have no practical experience of what they're studying. I know this is the scientific process, and I respect that. But how applicable is the scientific process to management? Is there even a "science" of management?

So, like all my colleagues, I jumped through the hoops set in front of me as efficiently as possible in order to get the qualification.

I'm not saying it was worthless. I did learn a lot. The class discussions, hearing about other people's experiences, talking about specific problems and situations, this was all good solid learning. But the essays were not.
