Okay I have never taken AP U.S. but have taken AP Government and am pretty good with the U.S.'s involvement in wars (spanish american, WW 1&2, Vietnam, Iraq). would it be hard to get a 740+?
Yes that would be difficult. I HIGHLY recommend taking AP American before you take the SAT subject test. I suppose you can try, though, because it only costs $10 or something insanely low like that.
Yeah, I think it would be hard if you haven't taken AP U.S.
This year the tests dealt more with treaties and proclamations and geography and what not. A couple of quotes here and there, and scarcely causes of wars.
