Query: It's enough

Great!!!I used this book as the sole source for step 3 (sometimes a little bit of Crush Step 3) and was more than enough. Use it if you as myself were exposed to peds, gyn, psych and other stuff some years ago. The book is most current and well written with good pictures but does not get 5 stars because the questions do not reflect the actual USMLE-MCQ style but it was not a major problem.It is written in 5 practice test with total 750 questions that cover most of the topics tested in step 3; it is coming with a company CD ROM that to be honest I never used, has the same questions as in the book.In summary a great buy and was really good for me. You do not need anything else.
