The PMP exam is preceded by a short awareness session, and the duration of this session is 15 minutes. In this session you are made aware of the graphical user interface and how to use it; for example, how to select answers, how to mark a question for review, how to submit answers, etc.
I have always advised my visitors to complete this session as soon as possible and utilize the remaining time to note down important formulas, concepts, or draw a memory map. I tell them not to complete the awareness session quickly as it will start the exam immediately.
Now the situation is different.
You are no longer allowed to make notes on scratch paper during the awareness session. You now must wait until the exam starts. Once the exam starts, you can use the scratch paper and write notes.
