Pre-med vs. Engineering vs. Physicist

I’m a 17 year old junior in high school, MN. Interested in science and math, I’m trying to figure out what occupation I wish to pursue after college. I like all science courses, physics, biology, and chemistry but am not sure which one I’d like to major in. There are basically 3 jobs I’m interested in: doctor, engineer, or a physicist. I’d like to be a pediatric doctor (pediatrician), aerospace engineer, and I’m not sure what physicist.

Pros for doctor:

  • Help other people
  • Respect
  • A lot of money

Cons:

  • 8 years of school plus 3 years residency
  • Pre-med courses are very hard to get a high GPA
  • Have to take the MCAT
  • High demand, but competitive field
  • 75% of people taking the MCAT never enter Medical School

Engineering:

Pros:

  • Fun because always working with other workers
  • Pretty good money (often takes a few years to make a lot more money)
  • 4 years for degree, but more for phd, masters, more schooling
  • High demand

Cons:

  • Have to work your way up to make a lot of money
  • Don’t help people as much as doctors

I’m scared of going pre-med for 2-3 years and dropping out because of rigor or even after taking the MCAT and not being able to go to medical school.

Is it possible that I get an engineering degree after four years while taking the pre med courses required for medical school? Then, if I don’t get into a good medical school, I can become an engineer. If this is possible, then would I have to choose an engineer related to bio or chem, or would I be able to choose an engineering field with physics (aerospace engineering)?

Is this true for becoming a physicist? Instead of an engineering degree, can I study to be a physicist, and then go to med school if I want to? How does college work for physicists?

Yes, you can go to medical school with a physics degree as long as you have taken the prerequisite courses. These usually include 2 semesters of Organic Chemistry with laboratory. There are probably other recommended courses too.

As far as the physics degree in college. You will take a first year course sequence which includes mechanics, E&M and thermodynamics and then you will take Modern Physics, and full years of classical dynamics, electrodynamics, quantum mechanics and labs. The rest is pretty much electives so you can choose to take the organic chemistry if medical school is your goal.
