For me junior year wasn't a problem, it was my senior year that was way worse than i ever expected (basically my mental health went really bad for various reasons, but im recovered and doing good)

just do you. i took four APs my junior (and then seven my senior) and yeah i probably could've gotten straight A's if i had bothered to stay awake, but i didn't feel like it. so long as you pass the test and don't do lower than a B, you'll be fine. after all, in my experience i've found AP classes to actually be harder than college classes-- though this is partially because high school gives you like 90,000 grades and college boils you down to like seven.

My junior year of high school I took 5 AP classes (some of my hardest classes during high school were junior year), a college equivalent course, took a leadership position in this important program I was in, started a club, got a job, did an internship, and I started occasionally getting baked in the mornings/lunch and did more ignant things junior year than any other year in high school. I somehow managed to get my best grades during junior year too.

Now I'm a junior at a good university who wishes life could be that simple again. You need to challenged during high school. If not you'll be boned during college when it actually counts.
Also, junior year college is the equivalent of junior year of high school. The cycle will repeat itself.

junior year is killing me as well
i wish you luck friend

You'll be fine. Junior year started off as a struggle for me too, especially since I transitioned from no AP classes to 3. I felt really strained and outpaced at the beginning, but eventually I got used to the classes and the pace.
