Having sets is god dam awful, every subject apart from your options, so science, english, RE, Maths etc.
Y7 > Low sets because I was slow in primary, which leads to me being influenced by the wrong people who don't care for education/distrupted lessons etc
which then caused the rest of the years in school to be in crappy classes where I'm hardly learning, apart from IT where I was somehow in the top set.
It would of been a lot better if they changed it to something like, real motivated people wanting to learn in a class who are not quite at the A*/A level in one class, or a couple if a lot of people want to learn, A*/A people in another class, and the troublemakers/who don't want to learn in another.
Another good way is to get smaller classes, in English for Lang, I was boarderline D/E and got put in a class of 7 with the deputy head (she was an amazing teacher) and because of this, nobody messed about and everybody got on with their work, a long with this we had more support because we was a small class, and so I got an A in my coursework (previously getting E's in my coursework in the other class... tells you something) and C in the exam (foundation) which resulted me in gaining my C overall (I might of got higher, if I did the higher, but who knows.)
