I’m a rising freshman right now, and this is my plan for which classes I will take. I’m a good student, I had straight As/A+s all through middle school with ease.
Is this reasonable? Is it too much? Should I make any changes? (I can’t change the freshman classes since I already signed up).

Also, do you think I should switch some of my lower level classes to APs? I am really not sure how much I can handle though.
My daughter aced middle school like you and was nervous to start high school with an AP course, but her counselor and I talked her into taking one as a freshman. Turned out to be one of her favorite classes and she made a 5 on the exam, so her sophomore year she took 3 AP classes, then 6 junior year and 5 senior year. I’m not saying to do that. Junior year wiped her out, and it took her several months to recover and was awful. But what I am saying is that if your school lets freshman and sophomores take AP classes, go ahead and try one before junior year. The advantages at my daughter’s school were 1) she got to be in classes with the smartest kids in the school starting freshman year, so she found her peer group that inspired her from then on, and 2) the AP classes had weighted grades which helped her GPA, and ensured she graduated in the top 5% – a requirement at many universities for getting invited to the honors program, or being offered scholarships. Don’t overdo it, but consider easing into things by trying one AP class as a freshman or sophomore. Then you’ll find out if you can handle it or not, and know what to expect before you are taking three difficult ones as a junior. Otherwise, your plan looks great! Good balance of very interesting courses.
I’m a rising junior, and my upcoming schedule is way different than I would have predicted two years ago. You might change your mind as you learn more about your school and teachers. Just stay open to that. Don’t feel bad if you end up changing your plans a little bit.
Maybe switch out World History for something higher level? If your school offers AP Euro for sophomores, that could be a good option. If you want to have more academic/high level electives, maybe switch something out for a year or two of another language (in addition to ASL)?
But your schedule definitely looks good as is!
I think its good, but I myself would at least take one AP class before junior year, to get used to the work ethic. Because by junior year, you have a lot more weight on your shoulders especially with the SAT, but I understand if you don’t want to stress yourself out. 
It’s fine. While planning out your 4 years is great, as others have said, things may change down the line, not the least of which are scheduling conflicts.
If AP World history is an option for sophomore year, I would opt for that. If not, it’s still very solid.
I don’t know how similar our schools are, but I too aced middle school with literally no effort. However, high school is nothing like middle school. In high school you’ll definitely need to try to do well and take time and effort to do well ( subjects vary for everyone). Also, I thought I had my WHOLE high school career planned out this year as a freshmen. Boy, a lot changed and my schedule has changed. Contact me if you have any questions!
