As far an intro to business, I only used IC to study. I did take take principles of supervision, HR management and Org behavior, also using the IC flashcards, and alot of the material is overlapping, which helps to study for the intro to business.

I did find these tests to be passable using IC, so you should have no problem.........I have been out of the game A LONG TIME!!!, and if I can pass it, you will do excellent

Best of luck
