Another popular way of looking at the exam is to follow the tasks that have the highest potential for good marks.
Some tasks that earn you 2 marks for a correct answer (4, 5, 6 and 7) while other answers are worth just 1 mark (1, 2, 3 and 8). It can be beneficial to try and do these higher-mark tasks first and leave the rest for later when you start to get tired.
This might be the sequence to follow: 4, 5, 6, 7, 1, 2, 3, 8
Maximise your mark-earning potential by doing the more valuable tasks first and, from there, move on to the tasks where you have to work harder for higher marks.
