I'm not sure about the different types, but I can give you a run down on UT.
1st, 2nd, and 3rd year are primarily classroom/lab oriented. Once or twice per semester we do a week with no class, but either an application based learning exercise(ABLE's), or CE(forget what it stands for but essentially it's a week spent down in the clinics on something specific such as anesthesia). First year was mostly basics: physiology, anatomy, histo, and lots of infectious diseases. Second and third year are more oriented on body systems, skill sets(ie. radiology), or species specific(ie. avian med) classes. Fourth year is all clinical rotations.
