I would never presume to speak for the great
@Goro, but, speaking for myself, you are misconstruing what
@WedgeDawg did with the calculator. He assigned a value to a MCAT range that is subsequently weighted and combined with 9 other variables to calculate an index that is then meant to be used to suggest a mix of schools to apply to. To extrapolate that to assume that the arbitrary MCAT range cutoffs he used for that purpose implies that adcoms at any particular school use the same cutoffs to evaluate candidates is to misunderstand what WARS is all about.
Aren't you the one who posted on the Duke thread that the admissions dean told you that 510+ is all treated the same?
Trust us -- 519/521 is not a distinction that drives admissions decisions, anywhere. Too many other things go into how a file is scored for MCAT differences within the test's margin of error to mean life or death for anyone, anywhere, arbitrary break points in clever school selection tools notwithstanding.
