@yonceonhismouth - Thanks for the advice. I asked my counselor, who said that replacing AP Chemistry with Zoology CP will make my schedule go from “most rigorous” to “rigorous”. I still don’t know what to do.
@Shanban1607 - I don’t need to take an AP art, but I do need to take an art to graduate. AP Studio Art 2-D Design is not considered a difficult class in my school. I can replace it with Ceramics, etc., but AP Studio Art (aka Photography) sounds more interesting.
