Help! I have no idea what AP class to take Junior year...

Why not take AP physics1 Jr year, then AP physics C senior year?

Same idea: why not explore the hole field of CS junior year (csp) and then take CS A senior year?

APUSH is a definite"rigor marker" for college admissions but it’s not mandatory since you have other “markers”. It IS quite a high step or two above regular ush.
