Why do you ask?
I think it's more awful that the first high stakes exam in med school is Step 1. One that's less clinically relevant, and the first board exam that most of us have ever taken. I'd much rather it was CK - once we've taken a similar board exam already, have some additional experience under our belt (clinicals, shelf exams, etc). Like I genuinely, truly think that Step 2 CK is a way better and more relevant exam than Step 1 various ways so yes, I would 1000% rather have CK as the first high stakes exam.
Yes, I did change the way I studied for CK, but having a numeric score that was reported to residencies wouldn't have changed that. And I disagree that scoring lower on Step 1 means that your foundation is adequate. It's a licensure exam. By definition, if you pass, your knowledge is considered adequate to do the job. If that's not the case, why are we graduating physicians who don't have adequate knowledge? Again, there's no evidence your Step 1 score is any indicator of your clinical acumen.
Re: the MCAT, don't really want to dig into this argument here, but I'd actually be fine with a P/F MCAT where the passing line is set at whatever score is consistent with academic success in med school.
Didn't say it was an "ethical" problem, I'm just arguing that step 1 is not a useful test beyond assigning a numerical score that doesn't really mean anything outside of the residency application process. Do you really think a dermatologist needs to know more basic science than a hospitalist or PCP?
And my argument here is not based on my personal experiences. I am going exactly where I want to be for residency and my step 1 score literally does not matter anymore. All I'm saying is that we should base residency selection on things that are actually relevant to residency performance, and not on arbitrary measures that have not been shown to predict residency performance, how good of a doctor you'll be, etc.
