thanks for the info I know about the MD PhD program and it's interesting.It's definitely possible to major in physics and go to med school. If you do really well in the major it will make you stand out from the other applicants.
I also know a few people who majored in physics and/or biophysics who are now in MD PhD programs. You will be in school for a long time, but tuition is waived for medical school and you get a stipend. They are incredibly difficult to get into for this reason. It seems that the MD PhD is a good choice for people who want to be doctors but are also highly research oriented (although you definitely do not need a PhD to do clinical research).
