Qshake's answer might be applicable to the essays but I'd caution you regarding the multiple choice. When I was taking the exam, I had to use the 2010 edition with a specific interim revision. I had the original 2010 version and the interim pages separate in my book. I remember distinctly that there was a seismic question where the answer without the interim material was slightly off the one produced with the interim material. It was just enough that had i not had the correct sheets with me, I wouldn't have been able to get the answer.
