Literature definitely does not require the least amount of studying if you haven't read the selections that will be on the test. I'd say go for chem.
There are a lot of negatives in the sentence... are you saying that studying for the Literature SAT II requires reading the selections in advance?
How is that possible? I'm currently deciding to take Literature and IIC in October. I'll have to study a lot for IIC but I'll probably just take a few practice tests for Literature. I think I can probably squeeze another subject test in there. I am just finishing up CP (college prep) Chemistry and so I was maybe thinking of taking it. I'm doing fairly well in the class.. but I have to question the competency of my chemistry teacher. I have pretty much no problems with conversions between moles and grams and all the stoichiometric calculations and I can balance chemical equations, if they're not too hard. How much of the test is just calculations? How much of it is conceptual? I think this is probably my weaker area, mostly because my class was taught to memorize "key facts" over an actual understanding of the material. Are the questions generally straightforward or are they mostly word problems where you have to derive an equation and then solve it? Depending on how difficult the exam is (if I do take it, I'd like to get within the 700-750 range), I might opt to take it. But I don't want to study too much, maybe 3 weeks of light to medium studying tops. I realize I have a lot of questions, but if anyone could just give me the basic ideas and whether I should take it or not, I'd really appreciate it
