I have taken Principles of Supervision, Organizational Behavior, and Human Resource Management, along with the cleps Business Law and Intro to Management within the last 10 days. Those 3 Dsst's overlap quite a bit and are pretty simple. Get the Official DSST study guide if you need to supplement your IC studies.
I have taken Management Info Systems previously. It is not too bad if you have a IT background, I don't. IC is all I used on this one.
There are numerous posts about the difficulty of Money and Banking, so I would discard that one.
