What DSST History test to start with

[radconjohn]

Getting started back to finish up my Bachelors degree and was told that the easiest and quickest route would be a History concentration. I told EC I wanted to test out as much as possible and they said I needed the following DSST tests for my UL credits

Civil War and Reconstruction
Rise and Fall of Soviet Union
History of Vietnam War

I was wondering which one might be the right one to start off with, maybe the one with less difficulty.

Thanks for the help!
