I really have no idea what I am doing

[cromew]

Ok, so here's the deal (and forgive me if this post is comprised of questions that have already been asked). I was recently told by my adviser that I was missing a prerequisite (Macroeconomics) for classes I wanted to take this upcoming semester. The only reasonable solution that I could come up with was to try taking the CLEP test for this subject. I have to have the test completed by August 1st and really don't know what I am doing. I have purchased the Cracking the AP Micro/Macro book (closest thing my local bookstore had) and signed up for Instantcert. Can anyone give me general tips/suggestions about the Macro test or CLEP tests in general? Are all of the questions multiple choice?

Thanks for all of your help. Sorry if this seems scatterbrained
