Principles of Management CLEP

[nervous]

Ok so I've gotten through the first 5 sections of the IC flashcards, and know them fairly well. Most of them I can guess the answer, I guess b/c I've taken Marketing and Business Law classes. Anyway, I've taken two of the Peterson's practice tests with a 73/100, then a 71/100. I don't feel like I know a lot of them from the flashcards necessarily, but more common sense. I'm planning on taking the CLEP tomorrow (Thursday) after studying the last two IC flashcard sections, and taking the last Peterson's test. Do you think I'm READY??? Or should I wait, my graduation depends on this test! So I'm pretty nervous...
Oh btw I need 50/80 on the actual CLEP to get credit, Thanks!
