AP Math (Calc and stats), Computer science, and US government are relatively easy to self-study.
With the change in AP Physics, it would certainly be harder to self-study (I took AP P1 and it was a lot harder than AP Physics B)
I think both AP English classes depend how good a writer you are. If you aren’t, then it would be hard to self study because you don’t have a teacher to help you.
With AP studio art, there isn’t much to the class since you spend most of the time creating your portfolio, so self-studying shouldn’t be that bad if you know what you are doing.
Finally, the AP history classes are kind of hard to self-study just because of the large amount of material to know for the exam.
Otherwise, everything else seems to be in the right place.

AP us government and politics should be on the easy side. AP English language and Composition is Medium not easy

US Govt should be easy.

You can’t self-study AP Seminar and Research because the exam has in-class components.
Calc AB is medium, rather than hard. Language is definitely not easy…probably medium.

While I agree, the level of difficulty for any individual exam is quite subjective; what is easy for one student may be difficult for another.
