I sent a mail to the lecturers a while back. Here's the response:
Dear Student
The drawing of diagrams for this 2-hour paper (where we have to test a year’s work) is not that important that we will ask a substantial amount of questions on it e.g. Draw …… but be careful not to ignore all diagrams in total. Know what they are for, know why they are important and be able to “read†them.
You will not be examined on Chapter 8, paragraph 8.5 – 8.8, but study paragraph 8.1 and 8.2 and read (as for an exam) paragraph 8.3 and 8.4.
Kind regards
