Even the way this plan is being presented is odd. Why are all the APs written in capital letters? Where are the elective classes? Where is physics? Also, I have no idea what colleges would think about a bilingual kid skipping learning a new language. Seems like a missed opportunity to me. Didn’t he start a new language in middle school?
Regarding exploring interests in high school: Our high school runs an 8 block schedule. We have a wide variety of electives in arts and special interest academic areas. My STEMy kid took lots of STEM classes. My aspiring writer is taking writing plus some related classes. Obviously a kid in a 6 block school won’t be able to take many electives. But that kid has only 6 classes. Either they’re getting a lot more instructional time than our kids, or they have a lot of study hall time at school. Either way, they can spend a lot more time outside of school on ECs and pursuing areas of special interest. (But less so if they’ve been pushed into a laundry list of all possible AP classes that they aren’t interested in).
Regarding the number of AP classes being taken: I am not sure how it works at other schools. At our school, AP is the upperclass honors curriculum. We don’t have such a thing as honors 11th grade English or history. If you’re in the top quarter or so of the class, just taking the honors track in the academic subjects, you will graduate with 8-9 AP classes from that alone, and plenty of kids take a few more AP classes in areas of interest. I think parents are mistaken if they think a lot of APs is going to wow the schools.
I would have the boy look over the curriculum for all these proposed APs and decide what actually interests him. Remarkably, my daughter managed to get into quite a few top schools by pursuing what interested her and without AP HUMAN GEO, A.P. MACRO, AP ENVIROMENTAL, A.P. PSYCHOLOGY.
