Intro to World Religions DSST test- what to use to study?

[tiffy1693]

Ok, I am taking this test for the second time next week (I failed the first time) and am wondering what people have used to study? I have found a few resources, and was just wondering how effective everyone has found them to be. Or if you used something else and found that it was helpful, what was it?

This is what I have found:

• Idiots Guide to world religions
  
• Pass Your Class - DANTES DSST Study Guides through this it says if you don't pass you get your $$ back but I am not sure how reliable that is
  

I appreciate any help that anyone can give, thanks!
