US History or Government Exam for non American?

[amhutap]

Greetings,

I need to take a CLEP/DSST exam to fulfill course requirement for US government or History, have not studied any US history or government in high school.

I suspect these may be easy topics for most, and exams probably would be tougher. Hoping for recommendations on which exam in the following list may be considered more 'straight forward' for someone completely unfamiliar with the topic at hand.

i) Civil War and Reconstruction, DSST (Sounds interesting but feedback says quite tough)
ii) History of the United States I, CLEP
iii) History of the United states II, CLEP (maybe more familiar than ii as it deals with more recent events?)
iv) American Government, CLEP (Feedback says dry, could be interesting for someone completely new?)

Its been hard gathering confidence after so many years of being away from school, but these forums have encouraged me enough that I have attempted and passed CLEP Biology and DSST Environment and Humanity in the past couple of months.

Thanks so much for any ideas you might be able to share.
