    *phew*... Does that cover all topics, or is there a lot more to know? I know I've read around here about needing trigonometry and geometry before starting calculus. This is going to take a lot of self discipline...

    I'm probably going to buy a book or software that can teach me calculus (if there are any) if I make it through the pre-requisites. A lot of times I google up topics and watch youtube teachers since the book can be very vague and lacking explanation.

    A LOT of calculus problems require trigonometric knowledge, and a good handle on different trigonometric identities. From the theoretical side there's no actual trigonometry going on, but in practice you need to deal with trigonometric functions all the time in calculus, so you'll need to know what's going on with them.

    You don't really need a lot of geometry... as long as you know how to calculate the area of a circle and a rectangle and a triangle, and maybe some 3-d shapes, but those can be picked up as you go along.

    You probably will want to practice factoring higher order polynomials (rational root theorem, etc.). On occasion you'll need to factor a cubic or quartic (if you're unlucky) polynomial and will need to know how to find the first couple linear factors

    I'd also say the algebra of logarithms. That's what my Calc I students tend to forget the most.
