Does anyone have experience with this book? Is it worth it to buy?

I have the book... it is good, but if you are boards studying and you have U-World or another Q bank then I'd just use that. I used this book basically to just supplement some boards questions in with my school curriculum from time to time and used it during the summer between 1st and 2nd year to just go over the systems I had covered during MSI. I still use it from time to time to do a few quick questions here and there on subjects I might have just started studying and don't want to "waste" U-world on.
