Preface: This test is not as bad as it seems.
Alrighty.
As I mentioned, I don't think I knew about all the resources listed above. I simply took the Free study sheet and went through it section by section on Wiki. If I told you that I studyied for more than 3 days, off and on for maybe a total of 9 hours I might be on the borderline of telling a lie.
Keep in mind this thing is a DSST, and as such you don't have to knock it out of the park as it were. I would say that even with little study, 1/4 of this entire test will seem obvious to you. Another 1/4 can be pretty much breezed over by a minor amount of study. Realistically you only need to answer half the test plus a few more to put you over the top with a "C". If you want an "A" or a "B" I think a week's worth of study time using the stuff I listed and Kiwi's post, you should be MORE than prepared for this one. Try the free study sheet a few times, do a few more WIKI searches, and right before you go in stare at some maps or a globe for about 45 minutes. See where the countries are in relation to each other. That should do it for you. Let's face it, even if you don't pass, 6 months later you can hit this thing again far better prepared. This latter concept is not one which I think will happen, but it's there as a fallback.
As I tell all the folks on these forums, JUST TAKE IT! Get so you can rap off 50 to 75% of the material and go for it!
Personally the time I spent studying this stuff bored me to tears, I think if I had to sit through a monotone teacher or a really bad online course I would join the circus as elephant cleaner #2.
