This was the last Maths lesson for 5x1. Reading from left to right you can see various bits of Stuart Robinson, Nick Budd, Tony Isaacs, Brian Alexander (at a guess!), Bev Coaster, Chris Snell, Gerard Soverall, Tim Budd, Fran Chapman, Allen Moxham, Karen Fenn, Sue Mays, Julie Morley, and Karen Corney.
The photo was taken in Room 19. This was on the first floor at the east end of the south corridor. Maths was one of the three compulsory examination subjects (the others being English Language and English Literature). Naturally the forms for Maths were streamed and 5x1 was the top set. There was exchange of pupils between sets based on examination performance. The the "x" in the set name was largely to divide the year in two for timetabling purposes.
