If you stay away from the LSAT threads, I think it's better.
However, end of this week, early next, I think you see that all of the sudden some of those posters who knew everything suddenly disappear. Getting an "awful" 162 instead of their "target" 175 will often shut them down.
In school, 1L grades really help deflate some egos.
Yes, I imagine this will also shut some of them down. Basically, I think a lot of "overachievers" are used to getting good grades and it is through grades they define themselves. This might be a function of youth and/or insecurity. Maybe they haven't had other experiences in life with which to define themselves. At the end of the day, you will have LOTS of people used to getting As and Bs with only so many As and Bs to go around.
Honneyhush, I wouldn't worry about it too much. You are of course going to run into some egomaniacs, but who cares? Let them be full of themselves and you can just do your own thing.
