I never used it on my own but during my fourth year we had a board review class and that book was used as the basis for the class. The attending running the class made an outline of information for the boards based on it which I did use so I guess you could say I used the book indirectly. Never bought it myself though and I didn't use the questions. I'd say it is useful but it probably isnt the sole resource you should use. There was def stuff the book emphasized that I felt was low yield for the exam. Overall was ok though. In total I used the outline from my K&S based review class, psychiatry genius, and board vitals and did very well on the exam. I ended up studying quite a bit because I was paranoid of failing but it paid off!
