Our oral surgeon did the BS/MD program at the same school as referenced in post 32 on this thread. His personality type and maturity was not one to be a slacker. Some students do learn and do their best for the sake of learning. Many students with less maturity don’t put in full effort once they get into med school.
Oral surgeon is married to a MD who is a medical oncologist, so they both had high career goals and achieved them.
