<p>You don't call a professor...you call the admissions commitee. It sound ridiculous to me that they would <em>prefer</em> German. That makes absolutely no sense. Why not Spanish, French, Greek, Latin, Japnanese or one of the other languages offered? They are no easier. Of course if you spoke Spanish you're whole life and then decide to take Spanish in school you are not going to get any brownie points. But I see no reason why they would <em>prefer</em> German.
Yes you can take a language test instead of having to go through preliminary classes. This is especially easy at colleges. I'm sure they have a testing center at you're college. Ask about the language tests.
Most high schools and community colleges don't have such advanced levels of math, not taking Applied Calculas is not going hurt you. In fact, if you interested in pure mathematics taking a class in applied mathematics would be completely senseless. Just make sure to take an introductory Calculas course at least.
If you can, you should, of course, take both history one and two. After all, it's always good to know more history. </p>
<p>Again: don't talk to professors unless you're interested in applying to graduate programs...talk to the admissions reps!</p>
