So if we don't have to major in biology, what should we major in? Let's start by examining the data about which majors have the highest acceptance rates to medical school.
The top 3 majors are pretty close - humanities, math, and physical sciences majors all have a solidly-above-average (46-48%) acceptance rate. Sitting right at average are social sciences, biology, and "other" majors, all with a 40-42% acceptance rate. And bringing up the rear are "health sciences" majors.
What should I major in? It's one of those personal questions like, "Which person should I date?" that no one can answer for you. Sure, others can give you advice. "Your boyfriend's breath smells like cheese" or "That person is a total jerk." But in the end, it's your decision to make. What you major in is how you spend a significant chunk of your college life, so it's important to your happiness to (try to) get this question right.
The good news: it doesn't matter what you major in for getting into medical school.
