The LSAT is supposed to be the great equalizer for law school applicants. It’s tough for admissions officers to compare a mechanical engineering major at MIT with a 3.6 GPA to a communications major with a 4.2 GPA at Central Nowhere University. But everyone, allegedly, takes the same LSAT. So it’s theoretically fair to compare someone who got a 160 to someone who got a 152. The Law School Admissions Council (LSAC) takes great care to “equate” each LSAT, to ensure that, for example, a 160 on one LSAT administration means the same thing as a 160 on a different LSAT administration. So everyone takes the same LSAT, no matter which administration you take or where you take the exam.
