Ray,

I JUST took the Macroeconomics CLEP test this morning, and there were a few areas that were covered quite a bit that I wasn't expecting. Make sure to study up on MONETARISTS and DISCRETIONARY FISCAL POLICY. Of course, I don't know how many different CLEP exams there and the one you get may not have the same focus, but it doesn't hurt to be prepared just in case.

Also, be sure to really understand what will move the Aggregate Supply and Aggregate Demand curves left and right. There were a lot of questions related to that.

Make sure you know what the govt. will do to help when there is a recession or inflation (inflation: they increase taxes & decrease spending; recession: they decrease taxes and increase spending).

And the practice tests through Petersons.com are DEFINITELY worth the time and money - I would strongly suggest you utilize that resource, along with InstantCert.

Good luck!
