Meg Shakesheff, 17, is head girl of Wolverhampton Grammar, an independent school "There has to be one in every class, somebody ready to snigger and disrupt.
It's such a bore for students who want to work, it's so frustrating and you just want it to stop. I think it's always worth teachers finding out why a pupil is doing this, but it can take up such a lot of their energy and the ultimate aim has got to be to make the behaviour stop.
"I think there are teachers you just don't mess with because of the way they look at you, or their use of body language. I think teachers have to be firm, they have to give out the message that they are there to teach and that is what they are going to do. These pupils are just attention seeking.
If they won't stop, I think they have to be sent out of the class for the sake of other pupils."
