Although both law schools and med schools tend to weight the test score a little more heavily than GPA. (Berkeley Law in an outlier in prioritizing GPA over LSAT for the obvious reason.)
No doubt, as GPA is only ~half the battle (at least for law schools). MIT kids are really smart and since the LSAT is ‘learnable’, most any of MIT’ers can clear 17x on that test with proper prep. That opens the door to most of the T14, even with a below media GPA. One does not need to be above both law school’s medians for a good chance of admissions. But if an applicant is above both medians, s/he can plan on some serious merit money at those not named HYS (which are need-based only).
