I can field this one for you. I took all of the practice tests when I was studying for the 6 credit College Math CLEP. I did these in conjunction with IC. The Peterson tests were MUCH harder and more indepth than the actual test; at least the version I took anyway. There were many word problems dealing with statistics and probablility. As several other threads have stated, know your prime and real numbers, mean/median, decimal to fraction conversion (and vice-versa), know how to /*-+ fractions. I was amazed at how much I overstudied for the test, meaning there was very little Trig or Algerbra. I received a 58 but it simply counted as a Pass with no grade assigned. Of course my input comes with the common IC forum disclaimer that this was just the version I took, there may be other more diabolical versions out there. I would reccomend to overstudy for this one, with 6 credits at stake, it will be time well spent. Good luck and let us know how it went. Lee
