Because of Pre-Registration, I felt like my schedule could use a rate…
AP U.S. History
AP Language and Composition
AP Psychology
French 3 H
Physics H
Pre-Calculus AB H
Choir/Madrigals (Block Class) - responsibilities include gigs around town, caroling, etc.
would you say it would get too rigorous? too easy? Is there any advice anyone could give me about any of these classes?
Doable, I’ll give it a B in terms of how rigorous your schedule is.
APUSH- The new course can be done without reading your textbook (although it’s recommended to read). All you will have to do is memorize terms, describe what events occurred before and after of that term, separate each event into a specific theme (you’ll learn about the themes in class), and you HAVE to read critically (in the exam, it’s all primary documents, secondary documents, or propaganda with a couple of questions related to it)…so you have to understand what you’re seeing. APELang will help you with the FRQs.
APELang- If you don’t like writing, drop the course. Self-studying AP English, both lit & lang, are doable. This course is extremely useful in the future, however, it will be the most tedious class due to the amount of work (unless if you struggle in math, which I don’t think you are).
APPsych- Again, it isn’t necessary to read your textbook. Memorize the terms and apply it to real life and you will pass the exam.
Pre-Calculus- Just study until you know how to do the math (majority of it will be pure, but there will be some applied, such as vectors) in Pre Cal by heart. Majority who have taken it say that it’s the hardest math class (because it’s all maths in one course including trig, maybe a preview of calc if time permits). For me however, Pre Cal was easier than Algebra 2. I’m not a big fan of pure - indifferent about it, (future applied math/stats btw). Also, Physics H will help you.
I’m taking Physics Honors next year, and as for the rest I’m not - so I can’t give you advice on those classes.
Nice schedule because you have courses that go with each other nicely, but - good luck! 
I’d say it’s a doable schedule as well. I’m in a similar situation as you (I’m actually taking the exact same three APs). I know for a fact AP Psychology is self “studiable” since my counselor even recommended it to me. Everything said above, to my knowledge, is true as well. Good luck!
