Maybe that is why the DO pass rate on CS is 85%, 10% lower than USMDs. If you dont account for the 6% of IMGs who fail the SEP portion, their pass rates are almost identical at 83 and 85%.
Its not that you need a bunch of rotations, it is just you got to prepare correctly to not overlook details of this exam or misunderstand it. This exam is unrealistic as you said and all about checking off boxes and doing things their way. Doing so many things at once like studying for CK, CS, shelves, rotating without time off in demanding rotations, preparing your application, and traveling between different states can make many people rushing to meet the deadline vulnerable to these oversights. Right after the exam I was in an FM rotation seeing 10+ patients a day and essentially did everything and the attending would just write off on it. Got an A with a letter and was the top performer as I was in most rotations. Exam serves one purposes, $.
And thank you. The storm has passed for now. I'll have my 7th interview soon. That seems to be the number where most USIMGs are hanging around. Very blessed and grateful. Wish you nothing but success as well.
