Well my school is one where we have a combined curriculum with medical students, podiatrists, and optometrists. The average grades per program per test 99% of the time going from highest to lowest are medical students, dental students, optometry students, and then podiatry students. The medical students are by far more high strung and stressed because they have to get good grades to compete for a residency. My dental class with a couple of exceptions are really laid back and all get along well and as far as the dynamic between the med students vs. the dental students, well lets just say I have met some awesome med students and consider them my friends but have also met a couple of BIG DOUCHEBAGS. I say for the most part there is cooperation and friendliness and mutual respect between the programs but there are always going to be a couple of students that throw a kink in things.
