This is your basic book of LSAT Logical Reasoning Questions with a mini drill in the beginning. The drill helps and the questions are a whole section so you can put a time to it. The time goes by fast. And I mean really fast. So the only critique I could have is much more drills (and I mean alot more) to practice your diagramming. Some of the questions can get quite complicated trying to map everything out.
I do not know my score yet, but overall I was pleased with the 6 PowerScore Books that I have and am much better prepared then I was before reading them.
