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.
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.
Continuity mistake: When we see the pupils jumping the pommel horse during the PE lesson, Gripper does his jump and you can see there is a pupil with a dark blue shirt at the back of the queue, but when we see a close-up of the queue in the next shot, there is now a pupil with a light blue shirt at the back. Then when Richard Marks does his jump over the horse the pupil in the light blue shirt has disappeared.
Continuity mistake: Just before Gerry, Ruth and Cathy go into the toilets Cathy is standing on the left - the angle changes and Cathy is now standing between Ruth and Gerry. Later on when they ask to go outside to get away from the puddles the three girls are standing close together, the angle changes and they are standing further apart.
