Query: Practically useless!

I should have checked this area before I bought the book... tsk, tsk..Although you can use the tests to practice, I found that I was spending an enormous amount of time trying to understand why my answers were wrong. My conclusion was that the book actually contained MANY wrong answers! Since the author does not provide explanations, you can't understand the rationale in the (mostly wrong) answers! You will not find any advice particularly useful. I found "Cracking the LSAT" a much superior, worthwhile book!
