Quartiles are based on both preclerkship and clerkship (at least they were for my class, I'm a graduating MS4). Yes you get to see your MSPE before the school submits it to your ERAS app. It's pretty similar to the AAMC templateDang. So are these quartiles based on pre-clerkship? Or just 3rd year?
Mind if I also ask what year you're in & if A&M happens to show ppl a template/example of their MSPE? The AAMC has one (attached) but I know schools can diverge from it
