Anyone else ever taken Pre Cal over summer at a community college? How was it?

Planning on taking pre cal over summer at my local community college after it was recommended to me by several class mates. It will be a 6 week course over my summer break, Monday through Thursday, from 8 AM-10:30 AM. If anyone has advice for me it would be much appreciated.
I’m a junior in high school, currently in algebra 2 but I really want to get into a UC, so I am pretty behind in terms of rigorous math. If you guys think I should buy any prep books or any other advice to give me, I would appreciate it

Start working on the basics through Khan academy. You should have about one third to one half of the chapters covered by the time.you start. You also need to be rock solid with algebra2.
You’ll cover roughly one “regular week” of content per day. Expect an exam each week.

Plan on 4 hours of work every day AT A MINIMUM. Don’t plan on doing anything else those 4 days.
