Title: Five stars for being the ONLY useful reference.
Review: As the GRE/CS approaches, I must point out that this book is the only available material of any use, except for copies of the first two editions, now out of print. It is true that no solutions are provided; it is equally true that the questions one encounters on the actual exam may appear to share little content with the questions in this book, but they are indeed like these questions. Solving these will help you on the exam, point simple. The list of topics and their scope is reasonably accurate. That alone is worth the price of the book, because you will know what to study and you will see that your enemy (be it circuits or finite automata or whatever) can only bite so hard. The books (and earlier editions) have helped my students and me take this exam successfully. I wish there were a better book, but so far there isn't.
