That was a pretty intense experience. I thought my introduction to academia after 20 years was going to be tough and I wasn't wrong. A typical day had about 17.5 hours of 'work', less than 5 hours asleep and the rest eating and talking.
It was actually quite easy to keep going because of the intensity, the only day that was tough was the very last day because the pressure was easing off (no forthcoming homework) and the fatigue beginning to kick in after 6 strenuous days.
I thoroughly enjoyed the experience of learning, connecting with others in the same boat, and the feeling that I've made a good choice to 'improve' myself. In terms of learning, its very clear that a primary method is to extract the experiences of the students and facilitate the sharing of these to the others. We are a fairly experienced group of people so there is a lot of scope for this.
Having dabbled with the idea of an 'online MBA' for the last few years I think this is one of the things I can't imagine them being able to replicate.
One interesting fact is the average length of time people remain in their current position post this MBA is less than 18 months.
