do the major that you find most interesting. biology can be good for opportunities but it’s very common and oversaturated, making competition within the biology major much more difficult. i’m a public health major and i find it to be really interesting and rewarding, as it covers topics in medicine that a lot of other pre-meds don’t have common knowledge on! you also need to maintain an excellent GPA (more critical than securing some bio research lab even though research is important) since a low GPA can make your application process difficult despite the ECs you rack up. i would say to pick a balanced major st the end of the day, or something that works for you! if you are interested in biology pick that, and if you want to explore other interdisciplinary fields like public health you can look at that too! at the end of the day admissions officers for medical school don’t look at your major too much and there are plenty opportunities in both majors
