I prepared with usmleworld for the ccs and the qbanks, went over the material 3 times and missed passing by 8 points , have no residency experience, did my best-now i am conflicted about using usmleworld again, as one,i am sure i have memorized certain answers on the qbank part, as far as the CCS goes, i didn't find their software very clear to work with, several times, i had to call the staff to alert them about my pc freezing up after downloading their program-and also having issues with certain cases that froze-so all in all the CCS was a disaster, i failed in part due to this portion of the exam, all my mcq's were skewed to the right, the CCS was skewed gravely to the left-i have researched some options, not sure if they will be a waste of my time, efforts and energy, such as : exammaster, there is a tutorial service, anyone ever hear of them? they use their qbanks, i have always heard that kaplan or uworld are the BEST for this mcq section. i keep reading about dr red/archer, both are the same thing, to take their pay per view videos for prepping the CCS, of course no sample for me to consider purchasing...and finally bumba: www. usmle3bumba.com has no evidence of a workshop yet since too early in the establishment, but a bit skeptical as can be understood...i personally have been using kaplan qbook and ez pass for ccs-i need serious feedback that is not overwhelming, all over the place! thanks in advance!
