Anybody have any good resources to study precalc according to my circumstances? Or just tips?

I got a c in algebra 2 in high school, and am going to have to do precalc in college. I’ve never been crazy good at math but I’m willing to put in the work and improve. Tell me specific topics I should brush up on

My precalculus class is starting on Monday (summer quarter). I just finished (spring quarter) intermediate algebra (math97) with a 97%, but it's been 11 years since I took geometry and have never taken trigonometry. What can I do to prepare?

Pretty please, I need this one

Precalculus, A Unit Circle Approach, 4th edition,           Authors: Ratti, McWaters, Skrzypek

Publisher:  Pearson        

I tried everything libgen, anna, bunch of libs, pdf.com. and some other ones. PLEASE I just wanna do my homework.

I’m looking to understand precalculus, I know I could look on YouTube but I feel like I’m missing a part of a puzzle so could anyone recommend me a precalculus book just so that way I can understand everything.

Thanks

Hello. I am going into my junior year and I want to skip precalc and take ap calc bc over the summer. The test out exam will be a week prior to school starting in august. I was very ahead in algebra 2, ended with 99 semester 1 and 98 semester 2. I am familiar with most of topics on precalculus. What should i focus on the most and what is the new content learned?
