Check it out. It covers:

-Principles of Supervision
-Intro to Business
-Human Resources Management
-Organizational Behavior

I have taken Human Resources Management and Organizational Behavior and passed them with no difficulty. I actually used the material from the Intro to Business and the Supervision sections to help me prep. It has practice questions for each of those, so if you're scoring over 60% then you are probably good to go.

I can't comment on the rest, except to say that a quick forum search will show that Principles of Finance appears to be a very difficult test.

Hope that helps.
