Student Seeking Beginning Calculus Advice I am a junior in high school and I am seeking advice on where I should begin learning calculus. I have just completed trigonometry as a school class, and I have to admit I enjoyed it. During the course, I consistently felt that learning trigonometry through school was too slow, and it made me want to start learning mathematics on my own. I am fascinated with math, and I want to begin learning higher-level mathematics as soon as possible. As you can probably see, I am a complete beginner when it comes to knowing about the different calculus classes. I do not know the difference between any of the different calculus classes and I am simply seeking guidance as to which one I should begin first.
I would appreciate any advice you can give me.
Thank you for your time.
Note: This question is not limited to calculus advice. I am merely looking for guidance on the next step I should take in my mathematical career. If that means combinatorics, abstract algebra or something else that is unrelated to calculus, I completely welcome that as well. I have just been told that calculus is the most reasonable next step.

Calculus is not necessarily the most reasonable next step.  I don't advise self-study in calculus, because there are so many subtleties that aren't obvious to a student.
Find a good book and read it, and do as many of the problems as you can.  One of my favorite books for general math, accessible from many levels, is Mathematics: A Human Endeavor by Harold R. Jacobs.
