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.
