Drug Reps are a good resource for inside track for clinicals (peds). Attendings general like them and they treated to nice dinners so an extra student sometimes is no big deal. As a third year student doing core clinicals I helped a nurse lift and transfer a patient. She thought that was very nice and I told her I might have to go to New York for OB-Gyn. She told me her best friend was a secretary for the head of OB-Gyn at Mount Sinai in Cleveland. I know this sounds like a line from Ferris Bueller. Three weeks later I am rotating next to Case Western students. You have to be willing to ask for favors because the clinicals are in short supply.
