Comparative Government Self Study Test Site?!?

Hi all,
I’ve been self- studying AP Comparative Government this year and am 500 pages in the textbook, and have been recently looking for a high school that offers it to outside students. I haven’t been able to find a single one within a couple of hundred of miles of me and it’s really ridiculous - college board has been no help at all
for all of you who studied comp. gov in previous years or this year, where did you take it? I live in Orange County, CA.
