will this be too hard for a junior

Hi, I am a sophomore right now and I am taking these classes:
Honors algebra 2, anatomy and physiology, Spanish 3, honors Chem, honors US history, and AP language and composition.
I am doing fairly well right now, I’m ranked in the top 50s out of 600 and my GPA is maintained at a 99
Next year I want to take
AP Literature, AP Pschology, AP Chem, AP bio, honors pre calc, Spanish 4

I just wanted to know if my schedule will be too tough for me next year.

*note: I like bio and Chem is okay, I don’t always understand it at first but when I do I’m fine. AP Comp is not too tough for me and psychology interests me even despite its large work load.
thank you!

Not just for a junior, but for all students - taking AP Chem and AP Bio is not a good idea. These classes are among the most intense and time-intensive AP classes (esp. with the labs). If you want to double up in science, I suggest you take either one of those + Ap Physics 1 or Honors Physics (or even regular Physics - you’ll need all three of bio, chem, physics.)

So:
AP Lit, AP Psych, AP Bio OR AP Chem, Physics, Honors PreCalc, Spanish 4.

I agree with @MYOS1634. Taking AP Chem and AP Bio concurrently is not smart. I have not taken AP Chem, but I took AP Bio last year (sophomore) and it was time-intensive. If it takes you time to understand chemistry concepts, you may have trouble with time management.
A physics course or AP Environmental Science (if you really like biology) would be a good addition to your schedule.
