LSAT Books for GMAT Verbal Prep
LSAT books, particularly Powerscore RC, Powerscore LR, and LSAT SuperPrep, can be effectively incorporated into one's GMAT studies. I used these three books and, in my humble opinion, the RC questions are excellent. The LR questions are also good for practice, although some question types do not appear on the GMAT and are therefore out of scope.
LSAT questions are considered more challenging than their GMAT counterparts. Indeed, most LSAT test takers usually comment on the disparity between the two in terms of difficulty level. LSAT RC passages are longer and can be much more complex. The actual RC questions can also be quite tricky. Simply put, the LSAT tests your RC skills to the max. The LR also offers a strong challenge, but this is partly due to the wide range of question types - some of which you will never see on a GMAT test.
If you're searching for practice only, then look no further than the LSAT SuperPrep. This book may be overkill for some, but it contains 250 questions and explanations relevant to the GMAT (150 LR, 100 RC). And the price is reasonable. Another option is to simply visit the GMATClub forums and practice with LSAT questions.
I would, however, advise you to pick either the Powerscore LR or Powerscore CR - not both. The LR version is identical to the CR book, except that it's much larger and covers more topics. Purchasing both the CR and LR would be a waste of money.
It's also worth noting that Powerscore LR and Powerscore RC are expensive, difficult, and take a great deal of time and energy to finish. Don't underestimate them. Purchasing these guides becomes harder to justify once we remember that Powerscore CR and Manhattan RC are available and specifically catered to the GMAT.
