Aspirations for the future...?

First of all you're 14 so it doesn't even matter what cles you take. In high school, NORMALLY you should just go out of your way to take care of the stuff you HAVE to do. Such as get your required sciences and go a little further. Like, if 3 years of math is suggested, take all four, and take 3 years of a language instead of just two. This is because the only people looking at your High School grades are going to be colleges you want to attend. And since you're looking at the medical field you really do need to excel, not just good grades but great ones. Do the best in all your cles, and take some that may relate to medical sciences, such as an anatomy cl, but for the most parts, you won't learn anything majorly important in the medical field from high school.
