Start at the back of the paper .For the same reason as the post above .
I did this on my second attempt and got 85% .
I finnished with 10 minutes to spare .So I had time to check answers .
Also they use the words useful load and usable load in the exam and there is a difference .
I simpathise with your plight .I have failed POF twice so I gotta get it in Nov.
Best of luck
