DS7 is in another expansion. He is learning quite a bit exploring on a paper trade account. He is ready to learn how to read balance sheets, cash flow statements, etc (US based) and how they are related to each other. Most of the stuff I have found is written for upper college/ grad which is a bit too advanced. Anyone have a favorite source?

Note: Dummies books and Idiot Guides are not a big hit here. Not sure why.

Thanks!
