Query: Unnecessary frustration

My satisfaction turned to red-faced outrage as I discovered an answer to one of the tougher logic-game questions to be "wrong," with an explanation that MADE NO SENSE.But that's because there are mistakes in the book. Imagine that. This oft-cheeky and blithely-clever text fails."Hackney" is only half the story: It sets you up to get wrong answers. I would have been better off spending $19.99+tax on a sweatshirt for a dog-- and I don't even own a dog!I am now dumber for reading 70 pages of "LSAT for Dummies."And I certainly won't be picking up "Baby Massage for Dummies."
