I've found the point allocation for the questions for all my exams last week a bit strange. Performance, for example. The later graph question with the answer 175m (I hope), couldn't really have had any other answer, there was nothing tricky about but it was worth 3 points. The earlier one with the answer 525 was only worth 1 mark yet the answer spread was very close - i did it four or five times always arriving at the wrong answer, 440.
Same with law.. all sorts of simple seeming questions worth 2 points.
Anyhoo.. a tortuous 2 weeks awaits.
