I live in Europe but have a US high school education. I need 3 CLEP tests with a score of 50+ to qualify for university here (biology must be one of them). The biggest issue is that I need to be certain I can pass on the first try, as I have to fly to another country to take the tests and there are time limitations. I've decided to take the Analysing/Interpreting Literature test since it seems so easy, but am unsure about the other test. I'm considering one of the math tests since I did quite well in school (A in AP Calculus, 740 on the math SAT), but it's been 10 years since I graduated and I definitely don't remember everything. I've read that College Math is easier, Algebra more focused.. which would be the surest bet if I only have a month to prepare? Or since I've already prepared for the Biology test, would Natural Sciences be better? I'm fairly solid in physics, but chemistry is a (very) weak point..
