Group Structure: Is it compulsory

I doubt very much that it attracts any marks at all You WILL need it when you move on to P2 and, if you were on one of my courses, I would INSIST that you draw the group structure After so many years of teaching this stuff, my lectures reflect what I consider to be the safety way of tackling these questions but, hey, if you think that you have a better approach, you go for it Good luck!
