I purchased this here the week before last. I am selling it now that my exams are over. There are four sets, with the 4th set unused. The others have faint writing on the questions, but no answers are written. Includes CD. Played a few weeks ago. Answer sheets remaining: 2. Answer booklet detached. I am also selling other reference books, so bulk purchases are welcome. Please feel free to comment. Please purchase only if you understand that this is a used item and has been stored by a private individual. Please read my profile if you wish to purchase.
