>>13086283 For mechanical purposes: Know the difference quotient, know how to factor polynomials, be good with multiplying by conjugate, know your trig identities and the values of trig functions evaluated at the special radian values, just generally be savvy with algebraic manipulation of shit
For conceptual purposes: be good with graphing, understand the concept of slope, be able to actually look at a graph and tell if its increasing or decreasing (shockingly some people struggle with this), understand piece wise functions.
A lot of calc 1 in a lot of schools is just memorizing derivative rules and being able to use them. The limits in the beginning are easy as fuck if you know your algebra and trig. Related rates and optimization fucks with students the most in my experience. You might get some more graphing with extra steps, if you were good before at it you'll be good again (so long as you can take the derivative, which is easy). Integration in calc 1 is also usually easy if you were good with the derivatives
Overall, calc 1 (in most schools I've seen) is a bit of a joke. I didnt cover everything you'll learn (limit definition of derivative or integral, IVT, MVT, etc) but you'll probably be fine if your fundamentals are good
