How do I become a doctor with a low sat score? High school?Also maybe any other career big money making ideas?

I don't know your area at all, and what's available for you in terms of colleges, but if you don't get in where you want to go, go to a community college for 2 years then transfer. You're going to have to do a bachelor's degree before med school, so there's time to get things going. Go to a website of a medical school you'd like to go to, then find the admission requirements. That will tell you what you need to study while in undergraduate school. This way you will have a game plan all throughout college that will help you reach your goal. If you aren't very good at planning schedules and what courses you should take, print out the requirements and take it in to your advisor every semester to help plan your course load. You may not end up at Harvard for med school, but you can definitely still go. Also, while in undergrad, look into workshops that will help with test anxiety so that when you take the MCAT you don't have the same problem.
