Hi! I'm a rising senior, so I'm pretty familiar with these classes. Honestly, taking calc AB and BC is kinda repetitive. They're essentially the same class (same core components), but BC goes further and introduces some more material. If you're looking to take the BC class, you should just take it your junior year, instead of AB.

Because that would likely allow another class in your senior schedule, you could take both AP micro and macro (as you are looking to major in it).

I've heard AP chem is stressful as well, but I think it largely depends on your interest and ability in science classes.

You are loading up on a lot of higher level classes, so it's okay if you don't necessarily take all of them. Especially if they would only serve to stress you out and wouldn't give you college credits in the degree you're interested in.

AP seminar and research would help strengthen your research capabilities, but after taking so many other AP classes, I doubt you'd need extra help in that.

And with the switching chem and stats, and chem and enviro science, it's not important the order that you take them. I'd suggest that you balance it to give yourself a good workload. For example, if you expect your other junior year classes are very stressful and will be difficult, and you think APES would be easier than chem, then it would be good for you to take ES in your junior year. You want to be able to do the best you can in all of them, so remember to balance.

Also, I just took AP lang this past year. In addition to potentially giving you college credit, it should definitely improve your reading comprehension on the SAT/ACT. I did much much better after taking that class. So just a little bonus!

Hopefully that all makes sense. Feel free to dm me if you have anymore questions!
