I applied like bananas to as many schools as I could (~70). So I feel like I gotta pulse on what many had in their secondaries & I can tell you that ~10%, if not a little more, asked if I had an acceptance before from a med school, whether that was asked on the secondary or sometimes at a later stage of the game. Idk if AMCAS has some system to flag this to schools already or not, but if schools are independently asking, I'd assume not
Would be more than happy to talk through the details of this school if you wanna PM. Personally, I could count on my hands how many schools actually have CONSISTENTLY nice administrations, at least that I applied to. Some schools have nice administrations but MY GOSH, they have the worst grading schemes I could even imagine. I've come to realize that it's hard to know what schools are the ones with all the nitty gritty details like nice admin, a thoughtful grading system, etc until you apply. And by the time you find out, the cycle is probably at the stage where few IIs are being sent out
