I'm just being lazy.

I found something useful while I'm studying for this weekend finals. I can't be bothered to open my books so when I need to review or document a particular concept, I just google it. And look at what I found: QuickMBA: Accounting, Business Law, Economics, Entrepreneurship, Finance, Management, Marketing, Operations, Statistics, Strategy
All the stuff we need to know are there and very well and clearly summarized in just a few pages instead of having to go through pages and pages of longwinded litterature. I'm SO damn efficient!:-)
