<p>Does anyone have tips about what to review, study, go over, and all before the test. I need to do well on this and I think I can if I clarify some stuff. I'm still so confused about the problems involving circle and ellipse equations as well as permutations and probability. Can someone help me out? Thanks.</p>
<p>Permutations is where ORDER matters (1,2) and (2,1) are two different possibilities. Combinations are where Order does NOT matter (1,2) and (2,1) mean the same thing. You should learn all those things you mentioned, but from what I've seen, you should focus more on Probability (definitely) and permutations; borrow a practice book and practice :)</p>
