I didnt see anything regarding management or maketing, do they still teach such things?
I think the best bet is to know enough about each functional area to know where to go to get the answers if you plan on running a business. Certain areas like accounting are great...if you want to be an accountant; same thing with finance. Forget law (sorry JD pursuing crew) if you want to be a lawyer, prepare for four more years post grad.

A thinker sees his own actions as experiments and questions--as attempts to find out something. Success and failure are for him answers above all.
