Should I double up on three subjects?

I’m filling out my schedule for junior year and I’m worried that I’ve overshot it. I’ve excelled in school thus far, and take honors classes. However, since we can’t take AP classes until Junior year, I’ve never had them before. Can anyone tell me if this schedule is relalistically manageable?
American Government
AP World History
Chemistry
AP Environmental Science
Algebra 3
Trigonometry (semester)
Spanish 3
College Prep English 1

It looks fine.

Is Algebra 3 just Precal? Your schedule looks fine.

Algebra 3 is prerequisite for Precal and or Calculus AB. Apparently it’s just a more in-depth version of Algebra 2

Why don’t you just take Pre-Calculus? Pre-Calculus is a slightly more advanced Algebra 2 with trigonometry.

I’d like to do that however my school requires you to pass Algebra 3 and Trig before they’ll let you take it.
