Self Study starting NOW??

I am currently a Junior in high school and unfortunately I just found this idea of self studying, and I am so drawn in by it. But unfortunately the tests are NEXT MONTH and I’m not sure if there is any AP that would I would be able to sufficiently study for in such a short amount of time. I was thinking AP Environmental, but even that I’m still unsure of. Is there any use in self studying as a senior? I feel so stupid for finding out about this strategy now!

Don’t feel stupid; it’s the strategy that’s stupid. Self studying will not boost your admissions chances, so unless you’re looking for potential college credit or are just totally enamored by the subject, there are better uses for your time.
