Winners of week five

  1. Team 7: 41
  2. Team 1: 37.5
  3. Team 5: 36
  4. Team 8: 33.5
  5. Team 2: 31
  6. Team 6:22

Alarmingly, there were 51 points up for grabs, and team seven scored 80 percent! That’s a pretty high score for a quiz night which is meant to be rather difficult, although I knew week five would be easier than the previous events, as I wrote the questions rather hastily. Still, the average was 66%, so things weren’t so easy.
