Your High School classes only have a value in gaining you admission to a college.
Anesthesiologists are doctors. It isn't the high school classes so much as the college classes that will get you into medical school. In high school you need good grades so that you can get into a good college. And in college you will need good grades to get into medical school. After medical school, you then study to acquire your anesthesiologist certification.
No high school classes, other then your core classes (math, reading, etc.) are required for a profession after high school
