Our school did actually separate us into sets based on 'ability' for all subjects including PE as an experiment because behaviour was so bad or some other shite. I was half decent at a fair number of sports but was smaller than most the year so was in set 2, and the problem was most of the bullies were in the same group. When rugby came around the had a legitimate reason to batter me, though even in badminton I still used to get smacked on the arse with a racket regularly. I **** hated PE.
