Principles of Supervision - amount of study time?

[Alaskan]

Hi,

I'm new to this forum. I have about 12 courses to finish in order to complete my BS at Wayland Baptist University and one of the academic advisors suggested taking the DSST Principles of Supervision test. Looking through the forum, it appears that this test is perceived as rather easy. I am running through the IC questions currently and wonder what amount of time I should devote to studying prior to taking the exam. Any feedback on what I can expect on this exam would be most appreciated, as well.

Thanks!
