I have no idea how I managed it. I am not even American, and have never studied American history. But somehow I got 10 out of the 12 of these right, and scored 450. 
Why not see how you do? :-
Maybe it is easier than it looks, but I impressed myself.
ETA: OK, maybe Iām not so smart. I meant to put this in MPSIMS, or at least Elections.
