Alright, something I can genuinely give advice for.
I took 5 AP's last year:
AP Literature and Composition
AP US History
AP Biology
AP Chemistry
AP Psychology
Honors Pre-Calculus (Same teacher as AP Calculus, teaches it the same way as AP Calculus)
For those of you saying it's Self Delete, you must not realize how competitive trying to be at the top of your class is. I'm assuming you're trying to get into a top-tier college (I just read the OP, not any of the rest of this thread), and if you're not taking at least 4 APs or 3 APs and putting that workload somewhere else (etc. a job or something like that) then you're gonna be behind.
Mind you, I took these 5 APs while balancing with tennis, DECA, Science Olympiad, Academic Super Bowl, volunteering, and tutoring. I'm a major procrastinator (didn't start my homework til 8 or 9 on a daily basis) and I survived.
Here's my tips (I got a mixtures of A's, A-s', and B+'s which I was satisfied with):
AP Biology - Ok this class is jackstuff easy, just follow along with what your teacher says and do the easy busywork assignments. My teacher gave out these big ass packets every other day (Like 20 pages of work) and they were all online and my entire class just copied them. Learning the material is easy enough, this class was an easy A for me and I got a 5 on the AP exam.
AP US History - My favorite class of all time. IT'S A LOT OF DAMN WORK. You're going to be reading every night, and the material is complex and tricky but really loving interesting. I'm glad I had an amazing teacher (best teacher in the school, everyone loves him) who knew how to teach it perfectly. If you put in the work (just read every night, highlight, read any extra documents your teacher gives, complete the homework) you'll be fine. Homework is easy for this class because it's basically just referencing to the text and copying down. I just stuck with this routine and got an A- first semester and A second semester.
AP English - Just go with the flow. You won't get that much homework, but you will be getting a lot of essays and reading assignments. Just focus on perfecting your writing everytime an essay comes by, and pay attention in class when your teacher discusses a read or something similar. I got by sparknoting most of the stuff we read with a background understanding from in-class lessons and got by with an A- and A.
AP Psychology - You will have fun with this class because in my experience its easy as forget. Like hilariously easy. It's basically quizlet for each test. But, my teacher emphasized reading with daily quizzes over reading assignments. So there's a decent amount of busywork and you have to keep up with the material. If you slack off, you'll be fine. I got an easy A both semesters
AP Calculus BC - Alright this class is actually really hard, I haven't taken it yet because we take it senior year but from my experience it is not easy. Best i can say is do your homework daily and prepare yourself.
AP Human Geography - Don't even consider this an AP. Literally the easiest class of my high school career my grade did not dip below a 98. Same thing as Psych, quizlet and just keep up with class material.
You're gonna have a lot of ups and downs (more downs than ups). It will be tough, and you will have moments where you feel like absolute stuff and regret ever taking any of these classes. But, trust me, that's just how junior year is. You're gonna be stressed 24/7 but when you come out of it you will look back thanking yourself for taking challenging courses and putting in the work.
General advice from me is get study groups, get friends together who have the same classes, and overall just try to take every opportunity you can. Getting study groups can actually be super productive, especially in the case of reading and essays and math homework which actually applies to all your classes. Having friends who have the same classes feels great because you know people who share the same pains as you and it can be great to relieve stress by just ranting with them, or knowing that other people are in the same place. Taking every opportunity basically means that every opportunity for extra credit, studying, extra resources are loving heaven. Usually those are the things that make the tests 10x easier and you don't wanna miss out.
It will be tough, but it's not Self Delete nor is it going to be impossible. I just came out of my junior year and looking back I'm glad I took those classes. Going in, I thought I was going to get B's and C's. But I came out with solid A's and B+'s here and there and overall my college app is strong as forget because of it. My GPA is high as forget, and my standardized test scores complement them so now I'm in a fantastic position. I don't regret a thing.
My AP Scores;
AP Biology: 5
AP US History: 5
AP Psychology: 5
AP Chemistry: 4
AP Literature: 4
Funny thing is, my non AP class (Honors Pre-Calculus) was my hardest loving class. I got a B- first semester and luckily brought it back second semester with an A-. The teacher for that is a loving hardass and his tests were impossible.
