I think taking APs not offered at your school can be a good thing, especially if you’re interested in the subject. My school only offered two APs, so I took AP Government online and took the AP exam, which ended up getting me out of an intro gov class at Cornell (useful, since government eventually became my major). And I also think colleges like to see that not only did you take the most rigorous coursework your school offered, but if your school didn’t offer rigorous coursework, you went out of your way to find it.
