self study AP Stat or AP Psych

hey guys
next year (my junior year) I’m interesting in self studying either AP Stat or AP Psych, as this would be my last ap exam needed to get national AP scholar before applying to college. One of these classes I would take in school, and the other I would self study

  1. which AP exam is easier to self study? I’m both a strong math and science student so both topics are interesting for me and I think I will be able to do well, but I don’t want to spend so so much time preparing for it. Is one more conceptual, or more memorization, or anything like that compared to the other? What would you recommend?

  2. Do you even think it is worth it to self study? How good does national AP Scholar look on college apps (I’m looking at top tier colleges)? Would it matter if i get national AP Scholar (earning a 4 or higher on at least 8 ap exams) at the end of junior year vs at the end of senior year?

Side note: if you don’t think it’s worth it to self study, I would still be able to take the extra class (either AP Stat of AP PSych) my senior year instead.

If any of you have self studied AP stat or AP psych, please share your stories!

Thanks!
