This is a quote from the thread that I was referring to:
"I'm going to start internship in June and currently my plan is to go down the list of top twenty reasons for hospitalizations and read about 2 per week in the New England Journal of Medicine review articles and whatnot until graduation to give me a good base of 80% of what you'll be seeing. NEJM has a great clinical problem solving series (go to the NEJM online website, select Clinical problem solving series and leave the search blank) with about 100 case presentations with a expert workup as commentary to help us refine our approach to handling the workup and DDx of symptoms. I highly recommend it. The one of hematuria is particularly good."
I've been doing research for a year (in b/w MS3 and MS4), and have had little exposure to clinical medicine during that time, so something like this, at the least, may settle the nerves a bit, and at best, give me some confidence on the wards, but is certainly not a waste of time nor will it retract from "having fun".
