The school is irrelevant. AP curriculum is standardized across the entire USA by Collegeboard.
It's an AP level class. You're going to have to do extra reading every night, write Free Response Question answers on every test (and maybe even more frequently), spend more time studying the details, and possibly study for the AP test. I see kids do it all the time. I wouldn't personally do that to myself (even though I am doing it this upcoming year with AP Gov/Econ) but if you want the weighted grade or the free pass from a college class, go for it.
