I currently attend a CC or JuCo and I plan to transfer to UT Austin. I’m currently a biochemistry major should I change my major to athletic training or something or does it not matter?
Your major doesn’t matter at all for med school admissions. You won’t be looking for a residency in sports medicine until you’ve finished med school, and possibly you’ll have to do another residency in family practice or the like before you can add on sports medicine.
