REA study guide question/help

[moose]

Hi all, I have a question for those of you who also used the REA study guide to help prep for the CLEP. I am studying to test out on US History 1, and made it just over half way through the flashcard studying here. Just for fun, and to kinda see how I would do if I just so happened to take the CLEP test now, I took the first REA practice test and scored a 47% (yea, I know), but then it said I have a score of 55. From what I have read and understood, you only need a 50 or better to pass the CLEP? So a 55 would be passing despite missing more than half the questions? And, just for the record, I still fully intend on finishing the flashcards and REA study guides, just decided to take the first practice test for "fun".

Thanks to all who reply!!
