Curiously, that's around the age a kid will graduate primary school and go on to high school in the UK. The experience is very dramatic, but probably very different than it is across the Atlantic. A child who's 11 and in primary school, on top of the totem pole through age, is suddenly at the very bottom in High School, and faced with a host of new subjects. They also tend to emulate the teenagers around them, so talk about sex, smoking, drinking, drugs, all comes to the fore too.

Suppose TS background is America, I heard preteens can went to middleschool when 11-12 in many parts of America. In China mainland it's generally 12-13 and IRL I known youngest person went to middleschool is 11 but only her, now she's college graduated
