Paper 3 Long Question

Paper 3 always ends with a long discussion question. The time is one hour so allow 2 minutes per point, for example if the Long question   is for 12 points allocate 23 minutes. If short question is for 4 mark allocate 8 minutes. This will help ensure you spend the correct amount of time on each question.

=== Long Question (12 marks) ===

- Suggestions for the responses ---

… USE TECHNICAL VOCABULARY whenever possible and sensible.

… Your response to this question(s) should be 1-2 pages long, depending on the size of your writing.

… and it must be completed within 20-30 minutes, as there are other questions on the exam.

… Hence, you may only give partial responses to each part of the question.

… Be sure to address ALL parts of the question(s), albeit briefly, rather than one part in depth.

… Keep in mind that there are no "RIGHT" answers, but there are better and worse answers.
