We are on Unit 4 out of 9 in my AP Calculus AB class

Hi everyone! Well as the title says my AP calculus AB class is only on unit 4 out of 9 and it's already February. I looked some things up and everything says we should be on or finishing Unit 6 by now. This is my calculus teacher's first year teaching an AP course so things are not going well at all. I'm at the point where I think my only option will be to self study the rest of the units so that way I have a chance of passing the exam. Does anyone have any resources or advice to help me?? I'm genuinely stressing out.
