What high school classes do you need to be a teacher?
Take whatever classes your high school has that are part of its college tract. Once you graduate and get into a college with an education major, get a counselor to guide you through the process of taking classes and being accepted into the teacher education program. Make sure you do a good job student teaching and with your observation bloc.
Most high schools have specific classes for that specific job. I take a criminal investigations class at my school, but Crime in America and Criminal Justice classes are also offered. you could go and ask your teacher if you are in high school like me i think the one that you need to study the most is science because u need to understand all the scientist stuff :)
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.
