Currently taking calc1 and was in your spot. Here's what I did.
https://tutorial.math.lamar.edu/Classes/CalcI/ReviewIntro.aspx review your algebra or relearn it, focus on the trig and logarithms.
I haven't started integrals yet, but derivatives and limits have been easy for me so far. You just need to know how to redefine the function by factoring and rationalizing the denominator amongst other tricks. Lots of algebra. I forgot to review asymptotes too, that's gonna bite me in the ass when we cover infinite limits.
Anons told me I wouldnt need to worry about conic sections and series until calculus 2, but perusing through the textbook I see that the series crap shows up during integrals so I'll find out soon.
