I attend a kind of laid back private school in the UK, where the premise of the school is to have a friendly, positive environment. There's no school uniform, we address the teachers by their first name and there's only like 600-700 students from reception to year 13, so pretty much everyone is aware of eachothers presence. In my experience, there was a fair bit of subtle bullying, and not so much beating people up and stuff. For me, I joined in year 6, and from about year 7/8 to the end of year 11 people were really being quite mean to me, excluding me and mocking me etc. However, in year 12 we start our A-levels, where we only have 4 subjects and have basically free reign over what we want to study, and a bunch of people left and some new students came, and the bullying completely stopped; I was able to spend time exclusively with the people I liked, and some of the people who left were the worst of the bullies, so I really enjoy school at the moment.
