I'm wondering whether GMATclub has a list of errors in sample questions for the most commong study guides. I've browsed the lists and it seems that most people focus on a few books - Cracking GMAT, Official Guide, Kaplan... Well I've just started "Cracking the GMAT" from Princeton Review and I've come across a few sample questions that seem to be wrong. But I don't know where to look up if the answers given in the book are mistaken, or are misprints. It seems like this would be a good addition to the GMATclub site if it doesn't already exist here.
So, here is what I propose - two new threads (sticky?). One of threads would be a place for people to propose errors and misprints in the most common study guides. People would then comment on the proposed errors and the proposed error would be either accepted as a misprint, or the proper solution would be explained to the poster, telling him why it is not an error and explaining how to solve the problem. Then, if it was agreed to be an error or misprint in the book, the misprint/error would be moved to the second thread. This would provide a very organized way to catalog the errors in the most common study guides. Let me know what you think of this idea.
