Which SAT II Tests?

<p>I'm planning on taking the SAT IIs in May this year. I know for sure that I'm taking Math IIC and US History because I am in AP Calc and AP USH this year.</p>

<p>I'm also in Physics and AP English Language, and I took Chemistry last year and Bio the year before that. The only problem is that my school doesn't offer "Honors" classes really, and although I am in the math-oriented upper-level Chemistry and Physics, I doubt they would have prepared me enough for an extremely hard SAT II.</p>

<p>I was thinking of taking the Lit. test. Is it really hard? Or (just one more question) should I put off taking Lit. and possibly take it and Chem. next year when I will be in the corresponding AP classes (even though I'll only have had a few months in each class)?</p>
