While Goljan's audio follows his book fairly well, there is MUCH more to his book than his audio. I've seen a few of your other posts about this subject, and I think the answer to your question is that you don't need both Goljan and BRS to do well on the path questions. I haven't taken Step 1 yet, but I've read enough on SDN to see that people who never listened to a word Goljan said and used only BRS did extremely well. The opposite is also true.
RR path isn't something that can be breezed through in a few days. If you really want to maximize your path studying, use Goljan's audio and add that to the text of RR path. It seems a little redundant to use both BRS and RR, especially if you're crunched for time. IMO, it's better to know one source well than try and spend your time flipping through both BRS and RR. The benefit of using his audio + his book is that you learn pathophys. I'll also say that if I didn't have his audio, I wouldn't like his book as much. But his audio combined with his book is worth it's weight in gold, IMO.
