Lots of peds when i did it (that was in 2001). The cases i remember where a 10y.o. diabetic (had to do diabetic teaching and couselling), and an infant with GERD.
I hadn't examined a kid since 3rd year med school (i was a surgery resident) and had no clue. Still got 100% on the exam and the pass was around 60. Not sure how you really can fail that exam (although aparently people do)
