You might be too late to get a full prep course, but it's worth looking into.
I don't know if the course really helped me all that much, but it was definately nice to go into the test with an accurate understanding of what you had to look forward too.
For me, the game stuff took the most effort. I actually enjoyed the bastards, but I wasn't fast enough at them. The prep course I took suggested focusing on completing 2 or 3 of the problems with high accuracy, and going on with the others if you had time, but I don't think that really helped me too much.
In the end, it didn't matter, I got my first choice school in spite of my LSAT score, but you have my sympathy.
Now, if I can just survive this legal writing class.
