Sat Chem Subject Test Prep

I’m going to be taking the Sat Chem test this Saturday. I already took the AP Chem test this summer and did a Sat practice test this weekend. A lot of the content covered in the AP course was not on the Sat Chem test. Are buffers, Gibbs free energy, and electrochemistry on Sat Chem?

How was the Test for you? What topics annoyed you the most
