Another tip. You have some prep time after receiving the briefing papers. Use this time to make a plog, complete with radio frequencies, timings, headings and everything like you would do for a real flight. This means that all the info you need is in a familiar place and format, so that you don't have to search for it in the briefing papers. It also means you've already "flown" the flight in your mind, in a structured way, before starting the exam.
During my exam that 1-page plog and the sketchy map was all I needed. Not the multi-page briefing.
