Google LSAT correlation study - the first result (for me) is a recent one from 2003-2004. (Direct PDF link to this particular one: www.lsacnet.org/research/Predictive-Validity-LSAT-National-Summary-2003-2004-Correlation-Studies.pdf)The short version: There's a pretty strong correlation between LSAT and first-year grades; a better correlation between (LSAT + GPA) and first-year grades; and almost no correlation between GPA alone and first-year grades.LSAC spends a lot of effort making sure this correlation exists; if it didn't, nobody would care about the LSAT.I wouldn't take your initial struggles as a sign you should quit though, and that's pretty crappy of the teacher to say that. Fact is, the scores used in this correlation study are largely scores that were received after significant prep work. They don't do a correlation of 1L grades with people taking their first diagnostic test cold. (Though it would be interesting!) So high LSAT scores for many people also indicate hard work -- also a good skill for law school. Whether that is the aim of the test, of course, is irrelevant.
The average multiple correlation between first-year grades in law school and the combined predictors of LSAT and UGPA is .48 for 2003 and .47 for 2004....The median validity for LSAT alone is .37 for 2003 and .35 for 2004, compared with .29 for UGPA alone for both years.
Honestly, I can't understand why the correlation is taken so seriously. Law School Exams require you to write a three hour paper about a hypothetical legal scenario -- why wouldn't a stronger correlation exist between that and the forgotten LSAT writing sample? Why can't we grade your ability to write well and analyze like a lawyer? Oh, yeah. It would take too much money and effort.Moreover, don't bother with these correlations. You'll drive yourself crazy, or, worse, create self-fulfilling prophecies about where you'll end up.
The listening comprehension idea was a neat one. They actually had many people in rooms wearing headphones listening to recorded dialog that you could not ask to be repeated or whatever that they were asked to answer questions about on paper.
