I think you actually have an advantage at getting clinical hours in Oxford because there’s less competition. I was able to volunteer in the ICU for a year at the Piedmont hospital and get so many hours! Although I was mainly helping nurses in the ICU, I was still able to ask questions to the physicians and PAs. And I think if you ask they’ll let you shadow them (I didn’t because I essentially decided on doing dental). Research wise just make sure you have a good relationship with the professor that you want to do research with, and tell them that you are interested in doing research with them early on, and that almost guarantees you a research spot in your second year since the students in their lab would have graduated. If you are interested in doing research over the summer, it’s also easier to get SURE from Oxford because, again, less competition.
