Law School Discussion

I've decided to start studying for the LSAT once again, in preparation for the February test.  Although I'm somewhat happy with my Sept score, reading these posts in the past few weeks has made me wonder whether it's possible for me to boost my score.  I scored a 163, but even a 2 point boost would put me firmly in the "acceptance" pile in the schools I'm applying to.  I don't plan to register for Feb, though, unless I can consistently score higher by Christmas.  I wouldn't take the test unless I was fairly certain I'd score higher.  Worst comes to worst, I stick with my current score.

I've been averaging 163 before my Sept test, although I have scored as high as 169 in practice (but have gone as low as 159).  Is it unrealistic for me to average around a 168 by Christmas/New Year's with intense studying?  Is this really just wishful thinking?
