Any one used these book, The PowerScore LSAT Logic Games Setups Encyclopedia, Volume 1 and volume 2.
I have been using the main bible and the work book drill. Wondering if it worth to buy the setup encyclopedia, if i have the main bible and the workbook. i know it basically answer and explaination from 1-40.

These books contain explanations in the PowerScore style for the Logic Games in PrepTests 1-40. You must already have the Logic Games from those exams in order to derive any benefit from these books. (The text of the Logic Games themselves are not included in these books.)

So, if you're looking for explanations in their style, and you already have the Logic Games from those exams, then it might make sense for you to get these books.

I would save the money and use this instead:
