During my medical education, I have relied heavily on review texts, and have had good results doing so. Having said that, my results would be even better if there were more guides of this quality available.
Not only is this by far and away the best study guide I have seen for psychiatry, I would go so far as to say this is the best such text I have seen on any subject in medicine. It is clear, concise without being superficial, and makes great use of readily recognizable clinical vignettes to introduce the relevant concepts. Additionally, the well-laid out colour charts remove much of the pain of the rote memorization that we all know is sometimes unavoidable.
A hearty "well-done" to the authors, and an unqualified recommendation to my peers.
Good luck studying!
