Thank you! I may have this one possibility. I think it probably is highly location-dependent. It also sounds like things have tightened up in recent years. I'm kind of irritated at the total lack of attention paid to this problem by College Board. They are happy to take homeschooler money and encourage the exams, but leave it to families to figure out a possible location. There's really no reason that AP exams couldn't be offered in general testing centers like the SAT is.

How are you guys finding local schools for your children to test? It has been almost impossible (have one lead that may work, far away). Everyone is saying it's only for their own students. My son is enrolled in the AoPS Physics 1 course, and I also asked our local brick-mortar AoPS. They said sometime in the future they may consider being a test site, but not this year for sure.
