Practice exams are updated only when the exam specifications are revised. If you order multiple copies of the same book, you will not get different questions in each book. If the 13-digit ISBN on a book you already have matches the ISBN in this description, the books are the same and you do not need to purchase another.
When will I get my book? Orders are typically shipped the next business day after they are
placed. Weekend, overnight, and holiday deliveries are not available.
