Boston and Baylor both use health profession committee letter to control who is and is not allowed to apply to medical school. UCB does not–anyone wants to apply can. Boston and Baylor use the HC to pre-screen applicants and only grant letters to those who the committee feels has a strong chance for med school admission.
So those acceptance percentages are artificially inflated.
Also be aware that most colleges have requirements that you take a minimum number of credits/classes in order to be granted a degree from that university/college.
Typically, it requires about 2 years of attendance to reach that minimum. That’s something you should investigate before making any decision to transfer.
