For those sitting Petet's wonderful exam paper find, the answers and much more are to be found in the superb AP129: Pilots' Flying Manual. I have both 1951 and 1955 editions, the most concise, clear and enjoyable textbooks I've ever encountered. I have even used some of the signals in our Tiger Moth trio formation.
These days, I find Fig. 16 "Opening Throttle" works well when alongside a boy racer at traffic lights, though I'm getting a bit old for this as well.
