I tell people all the time that one of the greatest things about the LSAT is that it’s remarkably consistent! That is, for the test to be considered a legitimate measuring device where people taking different LSATs can still be compared to one another in a meaningful way, the measuring device itself (the LSAT) absolutely CANNOT change! That, in a way, is the very definition of a "standardized" test. I mean, what good is a ruler if yours has 13 inches to a foot, and mine has only 12?
And while that may seem like a pretty obvious statement, think about why it's of tremendous benefit to you, the test taker.
