Maybe for a STEM major, but for Econ/Gov/Lit, most applicants to the tippy tops do not need AP Chem. I’m in the bay area and there are many local kids that get into the selective UCs without AP Chem. The key really is what non-stem APs the OP has taken. I’d be a little more concerned if APUSH and APLAC weren’t taken then AP Chem.
