Since there is a limited window in which one can get a JD
Other thoughts: As was said, anyone who can get nice score like 167 on the LSAT should be able to get a very nice score on the GMAT. Do not let your good GMAT score change your mind. Any bright person who is a good test taker should be able to do very well on the GMAT.
I agree with what was said about MBAs becoming less "special". I was surprised at how many idiots get MBAs every year based on my fellow classmates (I got a public school MBA a couple years ago). What someone wrote about them not being able to put together a sentence was all too accurate.
I was very shocked at how pathetic the undergrads were at my school when I went back for my MBA. I had to take a couple core business courses with them, they were horrible students. Backwards baseball caps, cell phones and stories about getting drunk and/or arrested is about all they had to offer. Pathetic. But many of you folks know that since you are in that cesspool right now.
Did I become a better student with my age (35 at the time)? Or did the quality of undergrads/MBA students go straight to hell? Probably more of the latter. In the end, I had to believe that too many people are going to college...it's the new high school.
