This was my response (lightly edited):
This is like Sudoku. Or the pools. Perm any seven. I don't do registers-- almost 50 years in teaching and I've never really got the hang of them at this level!
Still, there were 7 present, of whom two were women, and one was Kate because I picked up someone using her name to attract her attention. This week Adrian asserted he was there last week, because I thought he wasn't (it must have been the suit that fooled me). Keith definitely was. Jamal was. I deduced from some of the conversation that the other woman present was Lynne, because she is from PrivateCollege and wasn't present this week. Geoff wasn't present because he'd sent his apologies. Ted has a straight attendance record and I think I remember him. In the end it came down to a toss between Colin and Ahmed and I went for Ahmed because if I'm wrong it will have fewer consequences for him...
Who cares? Sorry!
