Is there a particular subject you had in mind? I thought "Robbins and Cotran Review of Pathology" was extremely useful during my organ systems. Even more so than the online Q bank I was using. It's essentially a pathology Q bank in book form, and some of the questions I saw on exams were very similar to the ones in this book (we have faculty-written exams).
I found BRS physio to be useful as well in helping me assess gaps in my understanding, but the questions are pretty basic and didn't represent what I saw on exams.
