I don't know how it works at your medical school, but here at the University of Washington, eons pass before the clinical clerkship evaluations make it back to the student. It's been only a few weeks since I moved on from pediatrics to family medicine, but my current roommate - he finished his first clerkship in mid August - still has not heard about his marks. This is a good reason to ask for feedback real time during the rotation.
What gives, UWSOM???
