I was wondering what people usually score on their first try.
The initial test is largely irrelevant. I would not review for it nor would I worry about your initial score. What matters is when you begin to study for the test. The first test I ever took resulted in a 145. I ended up with a 172.
I have taught the LSAT for over seven years - the initial test is one jsut to give you an idea of the hell you are about to face. The purpose of the test is really to scare you into studying for it hardcore.
If you have never seen the LSAT before and you sit down cold and take it, it is really not that helpful to go through the test and figure out what you have done wrong as you have NO idea of any solution strategies at that point. Once you begin preparation then you must absolutely go through the test and understand what you have done wrong. I have taught for three of the major prep companies and I can tell you that a review is not in order for the "cold test".
