Arnold Said:

after medical school, what specific careers would be open to me?

We Answered:

Different types of doctors. You would choose a specialty, and depending on which one you choose, you would do a required number of years of residency/internship. http://www.aamc.org/students/cim/about.h…

Do you get to choose the specialty of your choice after medical school?

We Answered:

It sometimes needs to be restated that you don't have to do a residency to be a licensed physician. All you need is a one-year internship.

Daniel Said:

Would civil engineering be a good major if you want to go to medical school?

We Answered:

You can major in virtually ANYTHING! It is a common misconception that you have to major in a science in order to be accepted into medical school. You can major in anything from Music to Art History, or Electrical Engineering, or even Slavic Languages and Literature! Pick something that you're interested in--majoring in Biology or Chemistry will NOT give you an advantage in admissions to med school. It won't make med school any easier once you're there, and it certainly won't put you ahead of your fellow med school classmates who were non-science majors.
While you can major in anything, you will need to take General Bio 1 and 2 (with labs), General Chemistry 1 and 2 (with labs), and Organic Chemistry 1 and 2 (with labs), 6 credits (2 courses) of English, and Introductory Physics 1 and 2 (with labs). Courses in Biochemistry, Genetics, Human Physiology, Calculus, and Statistics are also probably advisable. You'll definitely meet any math requirements if you major in an engineering field, and you'll probably also fulfill many science ones as well. You can work with your college advisor or the pre-med advisor at your college to figure out how to fit the other required/recommended courses into your schedule.
You'll also need to take the MCAT--most students take this exam during the spring of their junior year or in August right before their senior year. I recommend taking it in the spring of your junior year because then you'll know your results before applying to med school and also if you have to retake it, you'll have the entire summer to study.
