There are a variety of texts available. I have found the Anesthesia Review book by Faust to be detailed but an easy two week read. Starr's review is OK in its format, but I've had problems with some factually incorrect information in the content and it may be too light in the detail department. Hall & Jones question book is very complete and has good explanations for each answer to each question.
Medtext is too basic. Those are some off the top of my head.
