I disagree with Gdog in some respects. The powerscore weekend class is nothing you can't get form both the LGB and LRB. I bought both and went from 155 average to upper 160's in about 200 hours of studying. Its a real commitment to score highly on this test, but it can be done. What you have to do is read those books and think about all of the questions from a step back. Pay attention to common correct and incorrect answer choices, you will see those all the time. The weekend class can reinforce these ideas (I took it) but if 350 bucks is a lot, then you can skip it.
