I am too close to this and I am not sure I am seeing it rationally
DS14 went into a mock exam and one of the other boys in his class was so rude and disrespectful to him, DS said his mind closed in panic for a bit and he was so stressed he found it hard to concentrate and he thinks he messed up the exam because of this.
The other boy is part of a small group who relentlessly mock and be rude to DS, and the small group is part of a wider group and so it can be intimidating, and sometimes it gets pretty nasty with things being thrown and chairs being kicked.
If DS stands up for himself he is basically verbally mown down - the other boys and girls have no off button and so either DS spends his time standing up for himself, or spends his time focusing on lessons (which is what he wants). The same group are also rude to another boy, and both DS and this other boy are geeky in some ways. The same group are also sometime rude to teachers.
I have told the school a few times, what was happening and the effect it was having, and although they deal okay with more extreme attacks, and stop it, the low level constant nastiness isn't stopped.
WWYD? What would you ask the school to do? DS copes with it usually but it is wearing him down and he is really upset that an exam was messed up because of it.
