Well, what are you planning to do? I assume you are going to college- if you are planning to go into any kind of science, or engineering, architecture, etc. Take Calculus if you can- "precalculus" or "algebra" if you are not yet ready for Calculus yet. And once you have determined on a major, the math courses you will need will be part of the "required" courses for that major. In any case, talk to your advisor in college about what you want to do and what you are interested in. He/she will be able to guide you better that way.
