What do I need to know for SAT Chem, that wasn't on the AP Chem Exam?

Can someone give me a list/description of topics that I need to know for SAT Chem but not AP Chem?

If you did well on AP Chem, the chemistry SAT shouldn’t be any problem.

Collegeboard has practice questions!!! Do those. Link: https://subjecttestspractice.collegeboard.org/practice/sat-subject-test-preparation-chemistry?practiceTestSectionIDKey=Subject.CHEMISTRY
