remember there is no negative marking, so you don't lose points for a wrong or missed answer. Most people (I am told) will not complete the test in the 2 hours so try and relax and concentrate on each question rather than rushing to try and get more answered. I am also assured by a friend who sat it 2 years ago (and got an excellent mark) that you will get a higher marl of you skip completely the units that have you stumped and go back to them if you have time later.
