You're indicating then that 80 percent of people taking the LSAT don't try to do the work that it takes to get into law school or a good law school - including becoming informed.
The LSAT scores whether they are using the scale for this administration or the next are pretty consistent year after year. If they weren't and it was that skewed (yes, I get what you're saying about people doing better or worse but really, it doesn't change THAT much) the test itself would have no indicative value of law school performance because it wasn't consistently quantifiable
I don't know, do people real improve that much on the second run? I heard that they basically stay within the score band unless they didn't prep the first time and did a lot the next time.
So the point of that babbling is it is awesome you scored a 160+ on your LSAT. You obviously worked hard on achieving that score, but I think it is possible you have a knack for the test on top of the work you put into achieving a high score. That is just my opinion though. .
