Been a while since I was at school but there were some big stories.
The most dramatic to affect our year was what became referred to as "the purge" - when seven students in our year were all expelled for doing drugs, in year 10. Six of these were the most high profile characters in the year, four lads and two girls, and it changed the atmosphere of the year when they had gone. Those six would have made for an entertaining cast of Skins, they were all characters. I remember there being outrage at their 'unfair treatment' and made them out to be martyrs but, entertaining as some of them were, they couldn't really complain, they were caught with drugs on school premises. The one I felt sorry for was the seventh member, who had been a quiet studious kid in the earlier years and had just befriended one of these six and been introduced to rebellious activities, and sods law for him he got caught more or less straight away.
After they had been expelled, they achieved legendary status, and the four lads became studs. There were always stories about which girls from our year, or the year below, were involved with one of the lads from the "purge". One of them was this lad called Dunny, who dropped out of school and just worked in a pub when he hit 16, but during 6th form years, when anybody had a birthday or a night out, the social place to go was "Dunny's pub", just for the association with him. For the six troublemakers being expelled was a huge boost to their reputation and advanced their sexual opportunities considerably. The seventh lad, ended up with depression and in a terrible way, he was from a very middle class family and had brought shame on his parents.
Other headline stories from our school
The Head of English - an incredibly flamboyant 'silver fox' style older guy, who was the subject of multiple crushes from teenage girls despite him being 50+, ended up living out his fantasies with one of the students. Even though I was male I was gutted he was sacked because English GCSE classes with him were great fun, he was like a theatre director. I also remember this because his replacement was a very quiet young female supply teacher who got bullied mercilessly by some of the lads in our class, they ended up reducing her to tears.
In Year 11 a girl nearly died in hockey practice. She took a stray high stick full in the throat and it send her airway into spasm so she couldn't breathe properly, she ended up becoming unconscious and the PE teacher had to give her mouth to mouth. In the end an ambulance came and gave her an oxygen mask and she was ok. She recovered impressively quickly and was back in school the next day as if nothing had happened. The standard chat up line she received through 6th form involved "do you want some more mouth to mouth babes"
On the leavers' day for the year above us, a lad climbed up one of the buildings overlooking the school (not a school building) to paint a leavers message in giant letters, he got arrested and the school expelled him and didn't let him sit his exams lol.
