Meh as it is there way more high GPA than high MCAT applicants every year. We all love the narrative of how "there is all kinds of grade grubbing, grade deflation, and fierce competition" amongst pre-meds and that is true and there are certainly schools that grade deflate. I have no doubt about how difficult it is to even get a B(nonetheless an A) in some upper level's at the UChicago's or MIT's of the world. But in reality if we're being honest there's still more grade inflation going on in the general country that any form of grade deflation.
40% of applicants who apply to medical school each year with a 3.8+ cant even break 30 on the MCAT. When 4/10 people who apply with 3.8+'s are getting beaten by at least 30% of the general testing population( and let's be blunt at least the bottom 30-40 percent of the testing population has some sort of serious flaw from not being a good student, to absolutely zero prep, to not voiding a test when they should be etc) it just highlights that at many many schools pre-meds go to, getting top grades isnt nearly the obstacle people might think.
I've always thought for the MCAT really you need to cut out half the testing population to really see how you compare to others and even then therell be plenty of struggling people taking it. If you do it like that, a 31 is top 40 percentile, 30 is top 52, 33 is top 22 etc. So by that you can see once you start getting up to 33+ yes it really does become difficult. But honestly, when I see so many people with 3.8+s failing to hit a 30 or a 31, it does reek of grade inflation happening more than people might imagine.
