Power Prep is the older version of official mock tests for GMAT. As far as I remember, it used to come on CD alongside Official Guide, back in 2001 or 2002. I still have original CD with two Power Prep tests, fellow of mine gave me that CD couple of years ago. Power Prep was in the game while ETS was the official provider of GMAT. Once Paerson Vue took over the test - GMAT Prep came into the light. Basicly, these things are almost same - you can reffer to Power Prep simply as an older version of GMAT Prep.
How is Powerscore Logical Reasoning Bible (LSAT) different from the PowerScore CR
Bible (GMAT)? Does the LSAT one have practice questions? I read the CR Bible for GMAT and that book doesn't have many practice questions.
Hmmm, for this one we should have some ninja warrior who has done both books
I don't know the difference, I was using just LSAT book. That book is detailed and thorough, but doesn't offer practice material almost at all. Just dry theory and explanations, explanations and little more explanations. Boring and tedious for someone who is nearly proficient in CR but probably very useful for another one struggling with the same subject.
Pathfinder, you mentioned your CR hit ratio was improved after reading the OG, are you talking about the 2 pages in OG11
(Sections 8.1 - 8.3)? I don't see any other reading material about CR in the book.
No, I meant on CR questions in OG11
. After covering them and after reading couple of explanations here and in MGMAT forum, I haven't any problem with CR any more. I haven't even read those two pages that should have been some kind of CR introduction in OG. That is my point - ton of practice is usually enough for CR, that way you'll be able to capture the logic of test makers.
