Don't know how much this will help you, but I have not taken any courses...... I have been "studying" for a long time, but it has never been anything very serious, and it has never involved any strategy. I usually just practice problems from the "Master the LSAT" book. When september rolled around I started taking practice tests from the book "10 actual, official LSAT preptests" under the proper time limits.
First score I got was a 159.
Since then I have taken many more tests and it appears my score and the whole test procedure has improved (I am more comfortable, and I usually finish with time to spare). Practice seems to have really helped. Sometimes even when I am not sure why an answer is right, somehow I just know that it is going to be the answer.
Anyway, we will see tommorrow (October 4, 2003) if it has been worthwhile.
