Help! -- Need info of NJ/PA/NYC schools that allow outside student taking AP Chinese exam

Hello,

We are in central New Jersey (Somerset County) and are looking for schools in NJ, east PA, and New York City area that allow students from outside to take their AP exam in Chinese Language and Culture this May.

I called College Board many times but was placed on hold for long time and could not afford it during work hours.
Our high school AP coordinator is unable to help us, just told us to call around to find out by ourselves. I have called about 20 schools in NJ and NYC but was told they don’t take outside students for AP exams.

I’m still looking but would appreciate if someone can provide such information if they have the experience before.

Thanks a lot.
