In GMAT Ninja's
13-Week Study Plan (Focus Edition), he recommends using the Logical Reasoning (LR) sections in LSAT to practice for GMAT CR.
This post offers more detailed rationales. I'm also of the school of thoughts that LSAT questions are a great resource for GMAT Verbal, if you are pursuing an elite Verbal score or have run out of official GMAT questions.
However, I've seen comments on the Forum that some people do not have access to those recommended LSAT books in their own country. Also, because these books were published almost 20 years ago, it might not be easy for people to get the book in decent condition even though some copies are available in the second-hand market.
Luckily, I found out that there is a way for people to practice the LSAT LR questions, grouped by their original sections within the LSAT PrepTests, on the GMAT Club CR sub-forum. It's purely by accident, but when I was looking into the sources of CR-1000 Series, I was pleasantly surprised that the LSAT questions in the CR-1000 Series were organized by their original LSAT PrepTest section and each question actually contains a hyperlink. Therefore, if you just click open all the 25 or so LR questions in the same section, you can practice them one by one and complete one section at a time.
Attached is the Excel file with the question links sorted by LSAT section. This file was taken directly from the source file here -
Complete 1000 GMAT Critical Reasoning Series (CR-1000 Series) Question, so the credit goes to the GMAT Club team who originally put it together. I only did three things in my file:
1. Hide the non-LSAT questions in the beginning
2. Color alternate sections for easy identification
3. Add notes on the original LSAT PrepTest number and test date to those sections I can identify, FWIW
Potential benefits that I can see to practice these LR sections on GMAT Club CR-Forum:
1. Obviously no need to try to find those 10-LSAT-PrepTests big books
2. Practicing in familiar GMAT digital interface vs. on paper or over pdf file
3. Practice with Timer so your answers get automatically recorded in GMAT Club
Error Log. You can potentially group the questions from the same section together in
Error Log to track accuracy (haven't tried). You can also potentially analyze your errors based on question type and difficulty level.
There are in total 62 LSAT LR sections in the Excel file (31 Tests, ~1,500 questions). While there are a lot more LSAT PrepTests out there, what's in the file should be more than sufficient for most people interested in practicing LSAT to prep for GMAT. Hope this is helpful at least to some people, although the number might not be so big.
