Hi!
This is actually a ManhattanPrep forum, so the folks here might be a little biased. I was part of the team that wrote the guides, so I'm DEFINITELY biased
Our guides are a lot like Powerscore's in that they are a complete self-study experience for all three sections of the exam. I highly recommend adding our 5 lb Book of LSAT Practice Drills to your collection. It's unlike anything else on the market and a great supplement to any study plan.
I hope you like them!
