Hi Hazam, I did started with the knowledge areas chapter 5-13, then chapter 4. I won't mix up in the 2nd round and go by process group. For the 2nd round I suggest to always have the table 3-1 in front of you. It is important that you know to which process group and knowledge area the process you are working/learning on belongs to. You need to see the whole pciture, and be aware of what comes next and what has been covered already in the past. This will help you a lot to find the right answers in the exam, but also in daily work as a projectmanager.
