Your post history shows you are freshman in high school. It is nice to think ahead but really focus on the high school experience and make sure you have a solid foundation that prepares you well for college. Take biology, chemistry, physics and the math sequence your high school offers. Explore different career options and do research on different occupations in healthcare if that is an area you would like to explore. You are at least 8 years away from med school and a lot can change in that amount of time. Medical schools are not going to be looking at what you did in 9th grade.
In college you can major in anything and take your premed classes along with it but your first priority is to acquire the skills necessary to get to that point .
