In this guide, we’re peeling back the layers on the most popular branches of medicine and revealing everything you never knew you needed to know. Ready to explore?

The Importance of Choosing the Right Branches of Medicine

It’s a common misconception that if a student wants to attend medical school or pursue a more advanced job in healthcare, they must choose a pre-med degree. Your major is probably not going to be as important to most medical schools as your coursework, grades, MCAT results, and other credentials. To be admitted, some prestigious medical schools need a specific number of courses in subjects like English and the humanities.

Science courses are vital, but medicine isn’t just about textbooks and lab work anymore. Today’s doctors are expected to connect with patients on a human level, showing compassion and understanding beyond clinical facts. Exploring subjects outside of science, like psychology, literature, or ethics, can deepen that empathy. When selecting your major, prioritize the prerequisites for med or grad school, but don’t ignore what genuinely excites you. Passion matters too.
