I used FA/UW and RR. Honestly aside from a couple of questions (2-3), everything else was in the first two. As I saw someone say before, there is nothing rapid about RR and it takes two times to go through to be useful imo. Therefore it takes a lot of time to really utilize it. So if you have UW and FA down cold, by all means, this book will net you a few questions. However, if theres gaps in the previous two, you're better off mastering those then being ok in all three.
