However, in terms of difficulty actually achieving the scores themselves, you're probably right that a 250 and 260 are closer to 36 and 40 simply based on the med, vs premed, population comprising better test-takers overall. When I had first started prepping, I was naive/stupid enough to think a 270+ wasn't that much of a reach insofar as you put in the time/effort. Percentile-wise, a 270 is probably the 40-barrier, but in terms of difficulty, yeah, it's definitely a 43 or 44.
