Hi! Having a bit of trouble contacting my districts other high school. Mine does not have the exams I need-I was wondering if anyone knows of any (preferably central PA, but anything works) HS that take outside students for ap exams. I hope my district works out but I’m trying to form a backup plan because I’m anxious about running out of time.
Thanks, sorry if this question is annoying.
Have you asked you high school if they are able to order this certain test for you?
See this link- hopefully it can help
good luck!! 
We had this problem when one daughter self-studied for AP Spanish and then we had trouble finding a school that would let her take the exam. This was after she had studied at a Spanish-language high school in South America for a semester (her Spanish was pretty good). We eventually very politely threatened to enroll her in our local public school (which was not where she was studying), sign her up for AP Spanish senior year, sign up for the Spanish AP exam, and then immediately switch her back to her current (at the time) high school. This seemed to motivate someone at the local public high school to find her a spot – which happened to be at a different nearby public high school.
I suspect that the problem can generalize to other students, but I am not sure that our solution will work in the general case.
When begging and pleading, do your best to stay polite.
If there are any parochial schools nearby, check with them. Sometimes they are more flexible in having outside student sit for APs.
And the private HS’s as well. Agree with you- they are often less space constrained come test day.
I too was going to suggest private schools in your area - day or boarding.
Perhaps reach out to the local homeschooling group if there is one. Ask how they handle the AP tests.
