Plot hole: In this episode Mrs McLusky is horrified when Mr Sutcliffe suggests staging a girls versus boys contest and tells him that the school does not want to promote sexual inequality, but two episodes earlier (4-16) Mrs McLusky wouldn't let Trisha Yates choose technical drawing as an option, as it was classed as a boys' subject.
Plot hole: Doyle steals Alan's judo suit when he inadvertently leaves it in the corridor. Doyle tells Robo that he will leave it in the bike sheds overnight and will sell it to Junky Mead tomorrow. The next day Tucker arrives at school having bought the suit and says he saw it in Junky Mead's shop yesterday and bought it on his way in to school that morning.
Continuity mistake: In the second scene in the school corridor two girls are walking in front of Alan and Tucker, one wearing a black skirt and a black and white top and the other wearing a blazer and a black skirt. They walk up the stairs as Alan and Tucker stop and chat, a few moments later the same two girls are now behind Alan and Tucker and walk past them in the corridor.
Character mistake: In the meeting, Susi says that Penny Lewis and Rosie Spencer got in trouble during the previous year for writing a libelous article in the school magazine about Micky Doyle, but it was actually Penny and Chris Dukeson that got into trouble about that article about Doyle.
Continuity mistake: Tucker, Benny and Alan are in the hall for Mrs McClusky to announce the winner of The Competition to design the front cover of the school magazine. The shots alternate between Tucker and co and Mrs McClusky - every time the camera is on Tucker, Benny and Alan there are different people standing in front of them.
