Well when I was in school 10 yrs ago...LOL We had American History in 9th, World history in 10th, I dont think we had a history class our Jr yr but in Senior yr we had Econ and Government.
9th-World History
10th-Civics and Economics (Columbus - Revy War)
11th-US History (End of Revy War - Present)
12th-nothing unless you consider Psycology/Socialogy since it is a human studies class
I graduated in 2004. I had world history in 9th and 10th. It was a continuation of it in 10th. In 11th there was US History and in 12th there was economics and government.
I also took a few elective history classes in 12th grade.
