Currently I'm a sophmore who was wondering about the self-studying for AP exams. I don't have enough time left in my junior and senior year to take a few AP exams I've heard are easy like AP Psychology and AP Environmental Science. My school does offer these courses, but right now I'm working on getting my IB Diploma, so I need to take mostly IB classes.
Would it help my college application to get a 5 on these AP Exams if I self-study for them? Or is it not worth it?
In particular, how has self-studying for AP exams helped or not made a difference for people when they applied to colleges, especially top ones like the Ivy Leagues?
