However you should make sure you understand the background to why these are of such fundamental importance; see Study Pack sections 6.9 - 6.12 and then study Appendix G.
To check your understanding there is exercise 1A in Appendix W ; submit your answers to this.
Then attempt the activity in G23 looking at the 2004 layout . You'll find that some numeric answers are given as exercise 1B in Appendix W so to some extent this will allow you to check yourself. However don't expect to get exactly these numbers and indeed in the IRSE Exam getting the "right" numeric answer is not the "be all and end all"; hence submit your answer and pay attention to presenting in a manner that fully explains what and how you are calculating.
Submit your attempts to each as you complete them; I'll set the deadline to be 26th March .
Not exactly overwhelmed with answers to look at this weekend; never mind it gives me a chance to prepare something for the May Signet event instead. Someone has been polite enough to ask for a few more days to complete, so happy to accommodate because I understand the reasons and can replan.
Interesting simularity with the every day world of signalling project work environment I am afraid. Design dates tend to slip (and usually without prediction or even recognition that the deadline has passed), but the project's "end date" is fixed and the testers get squeezed into a diminishing timescale........
