Hello everyone, this is my first post on the forum!
PJW,
I attempted question 9 of Module 5 2008 without any prior revision in an attempt to gauge how difficulty the exams are. I compared my answers to yours and I realised that where I stumbled was not knowing that the ratio of release current to operating current for a track relay is 68%, I later found this in BR938. Could you please tell me how many marks do you think I would have lost if I stated in my answer that I assumed a certain ratio (not 68%) and used the same methodology to calculate my answer? I would just like an idea of how much weight, in terms of marks, is given in the exams to remembering such details.
Regards
Gethin
