I first bought this book in high school (sometime between 1999 and 2000), but I have used it numerous times since then. Currently I am enrolled in medical school, and it is one of my most important study tools, right up there with Netter's and Gray's. I highly recommend it. There are literally hundreds of questions on each topic, including head & neck, thorax, abdomen, pelvis, lower and upper extremities. In my version, there are numerous typos and one or two incorrect answers, so have a secondary reference handy in case you notice one, just to check yourself. But overall, it is very accurate and highly recommended in your test prep.
