Most of my 'performances' were border line, none were 'lower performance'. My CCS cases had one 'x' on borderline the rest were above. At least 4 cases on real exam were not on either of the CCS-banks, but not impossible. Many of the questions were extremely similar to UWorld Qbank. There was lots of "What is most frequent complication?" & "What's the treatment of complication?" A few "What's the natural evolution of the disease if no intervention is practiced?" There were a few Step Two drug questions using drugs' mech. of action as answer options. I had at least 10 Qbank style questions dealing with statistics-study them all as those are easy points:RR ARR and relationship of both.
Don't just study the questions' answers from Qbank. Study the complications of the diseases. I took another forum members advice and used the AAFP site for supplemental studies.
