Possible to switch major after being accepted?

Hi! I was recently accepted into UCSD Muir College as a General Biology Major. Would it be possible for me to switch to human biology?
Also,is there really a difference between general biology and human biology if i plan on going to med school?
Thank you!

The answer to your first question is yes! Once you get access to TritonLink in the summer, you can change to any nonimpacted major easily. I don’t know the answer to the second, sorry.
