If your goal is med school, then one thing you will need to focus on is getting the highest college GPA you can, including highest science GPA you can. That means you want to get as much preparation as you can in high school (i.e. don’t skip rigor because you fear the effect on your high school GPA). If your GPA drops in high school because you increase the rigor, you can still go to a good college and end up in med school. If your GPA drops in college, then med school may no longer be an option, or it might be an even longer process than it might otherwise have been.
In what type of environment do you do best? Do you prefer an environment where everyone is super strong and pushing the whole group to be the best? Or do you prefer where you’re in the top 10-20% where you’re getting a challenge, but you’re one of the stronger students? Think about that as you decide what type of school you want to apply to. Remember, that half of the students who go to any university as bio majors (or similar pre-med) are going to end up in the bottom 50% of their class, regardless of whether that’s Harvard or Directional State U. Med schools will want to see a high GPA, a high MCAT, and lots of medical-related experience (volunteering, shadowing, etc).
