168 ---> 147 is possible, with apathy and some rum.
On the LSAT score, are you taking a prep class? I took Testmasters and it was invaluable. Powerscore and Testmasters are two of the best. Our TM teacher told us about how in his opinion there are a few types of test takers as far as improvement is concerned. 1) Those who get a low diag and never improve because they are just not smart enough, 2) Those who improve alot on the second diag, after some training, but then plateau, and 3) Those wo improve a little bit each time.I saw this first hand and it was crazy! The girl next to me got a 147 on the diag, then a 158, 157, 159 and a 159 on the actual test. Another girl got in the 149 ball park and never got any higher! I got a 146 and then a 156, 154, 156 and ended up with a 155 on test day.I do not want to discourage you, but in hindsight I honestly believe that 160 was probably the highest I could have ever gotten, on a good day. Improvement is extremely hard the higher you go, and no matter how 'good' I felt I did I kept getting the same ball park score because of the nature of the test. Out of 60 students, we only has approx 8 break 160 and only 1-2 get in the high 160s/low 170s.I hope you are one of those few though!
Definitely doable. Me: 146 ------> 170 (December '05).
