AP Chemistry is one of the hardest AP classes that exist.
With an 89% in a class you barely remember, it’s going to be an uphill battle and you risk failing. And an F = being rescinded from colleges that admitted you.
So, ask your GC whether, if you take AP Chem in the Fall and find it too hard, you can switch to APES within the first (10 days?) of class. APES includes some chemistry and biology all applied to the environment.
