If your school has a 'pre-med' major then that's a different story.
But, to sum it up: there is a pre-med track.
2Semesters/3Quarters of : General biology, General Physics, General Chemistry and Organic chemistry. All including a lab.
With recommended courses of: Statistics, Biochemistry, Anatomy, Physiology, Microbiology (and/or Microbial/Virology), Genetics, etc.
Take the courses listed above.
Don't do Biology for the sake of getting into medical school... I know plenty of people who equate Biology major = premed major.
Study something you love! Undergraduate is like a buffet of your choice 😀
My recommendation for a major is:
are you interested in a rock or want to know about it? Well, contact your Earth/Planetary Science department today! Earth Science is so fun, you can major in it!
