If any major can become pre-med and eventually attend medical school, what is something everyone should try to retain from their classes?

Hello!

Many people that I know who went off to med-school were biology or chemistry majors. To supplement that some folks took anatomy or sport medicine type classes. Something that can be less obvious to communication skills. A doctor or nurse will often need to communicate quickly and effectively with patients. So, you could consider talking classes geared towards public speaking. Finally, take something fun! If you see an interesting class, go for it. I was an applied mathematics major, but I took classes on Chinese history and classical literature. 

Getting to the Med school is not easy. In addition to that, you must pass the pre-med stage. But if you're in high school then think of taking the AP classes and familiarize yourself with the hard content. Be comfortable to challenges. Int hat way pre-med will be easy for you and try to concentrate more on your sciences. Other wise, always ask your student advisor for more information. good luck !

Take the required science courses, and do well in them--no one can be a doctor without a deep understanding of science. But equally important are the humanities and the arts--history, music, literature. Learn music theory and/or how to play a musical instrument. Read the classics in literature. Learn another language. Learn the history of cultures not your own. All of this will help you relate to your future patients, to see them as human beings, and to bring context to the world(s) they live in.
