I want to have another class and I’m down to Ap environment science, ap cs principles, ap euro and ap art history. Which should I take?

You have a pretty rigorous courseload already, so I don’t think you should try to add another difficult course. I would go with AP Euro, as I don’t think adding another lab science is a good idea, and CS is pretty difficult.

CS would actually probably be the easiest because its CS principles not CS A.

AP CS principles would probably be the easiest (as the poster above mentioned) but if you want to have more of a variety go with AP art history. On the other hand, if you want to focus on a specific area instead of having greatest variety or easiest AP, go for it.

You have too many AP 's and risk passing for an AP addict to admissions.
Why AP psychology?
I’d pick between AP psychology and applying CS principles, based purely on your personal interstate for the subject, and take a fun elective, perhaps in art.
