Doubling up on science as a junior/senior in high school?

I’m currently a sophomore doubled up on Algebra II and Honors Geometry to get ahead of my classmates; our school board doesn’t allow students to take Algebra 1 before 9th grade.
Anyhow, I doubled up on math this year also because many of the juniors were complaining of how rigorous Chemistry 1 is while concurrently taking Algebra II.
When and what should I double up on in science? I am currently in Honors Biology. I took Earth Science last year and I’m aiming to take Calculus and Physics, which are foreign to many students and teachers at my school (very rural area, most students only complete Algebra II or Biology before graduating) before I graduate.
Thank you!

I’m doubling up this year. It’s great.

So if you have those classes available to you, go for it!

What are you doubling up on? I don’t know what to take.

Double up if you have a course available to you in junior/senior year that you are interested in.
For example, science is not my thing but history is; in junior year, I took AP human geo and AP US history together (in addition to the other core subjects). In senior year, I’m doubling in history again, with honors IR/honors asian studies.

You should take H precalc after Algebra II and before Calc.

You could take H Precalc and H Chem junior year. Then Calc and Physics senior year.

Can I take Precal without Trigonometry? If so, that’s what I’ll do.
