Introductory Sociology CLEP - Thoughts?

[originalamyj]

My daughter took the free Soc test from Free Clep Prep today and only got a 43%. Im not sure if we should buy the study guide from FCP or the REA book or what. We are not paid IC users because she's not actively taking a lot of tests, just wanted to knock out 2 this summer while she's dual enrolled at the local CC. I thought Soc would be an easy one for her because she likes psych/soc and aced her Psych class at the CC. What's the best (cheapest) study aid IYO? I think she will likely go through Modern States for the voucher too, so what should we do in addition to MS? REA or FCP?
