Should I take the U.S. hist exam?

<p>Okay so I am planning on taking the chem and math 2 exams this June and was wondering if it'd be a good idea to take the history as a 3rd exam, seeing as how I already payed the basic fee. I took U.S. history honors last year which covered up to the 1870's but am in U.S. History CP now and we're only up to the cold war. Do you think its possible to get a 700+ with 3 weeks preparation? I'm pretty good at history but am unsure if it'd be worth it.</p>

<p>Thanks in advance.</p>

<p>Sincerely,</p>
