To repeat what I've heard here and what I've discovered to be absolutely dead-on: The key to doing well on boards is to learn the most you can during second year. What also has been helpful was to take my own condensed notes from the course material, which I can then review quickly in May (now!!).
There is a lot of material, and unless you're a memory freak, you will probably need to see it many times and spend a lot of time on your own "figuring it out" and integrating. Goljan definitely helps with that. I also listened to Goljan throughout the year as we were doing the material in class.
I didn't find BRS too useful during courses as it wasn't detailed enough to do well on the tests. But right now I'm doing BRS + Goljan Rapid Review + Robbins Q-Book + Reviewing course notes, and I feel really solid in path. The Robbins Q-Book is outstanding at giving things a clinical presentation with very challenging, concept-oriented questions.
There are two things missing in that combo, however. First is pathophysiology. Especially in Renal, Respiratory, and Cards. For that, I'm especially grateful for my course notes. Some people like Pathyophysiology for the boards & wards, but I find this book easy to read: really small font and lots of flow charts that I don't feel like working through. Second is the pathology pictures. The Robbins Q-Book has some, and Goljan has some, but somehow I still feel like I need to skim daddy Robbins for more.
Disclaimer: I don't take the boards for another six weeks, but I've done well on the NBME assessments so far (240+).
