Personally I found FP was the exam in which I was most pushed for time = the one I felt most jaded after exiting!
As above posters have mentioned, it's about time management. If you don't think you can do a question straight away and do it fast, move onto the ones that you can. Also, keep your E(lo)s etc quick to hand, preferably somewhere on your table - I laid them on the floor and the way the questions were set out meant I was CONSTANTLY reaching and replacing charts of all sorts!
That's another method for the chart related questions - whatever chart you need for the first question, just go through all the questions relating to that chart, then move onto the next one.
All the best
