Have you got much classroom experience? I'd say draw on that alot as examples for things like behaviour management and different levels of abilties as they'll ask you about them.
You'll be asked to mark a peice of work written by a child, and give some ways in which you could help them to improve.
You'll also be asked to write a page about an educational issue, you can choose something from the list they give you or write on a topic of your own choice.
Finally, dont worry too much about it, have some examples in your head from your classroom experience and you will be fine!
and good luck! x
