Hi,
I had an interview in for the PGCE primary in mathematics, so obviously it wont be the same. We had to give a presentation as a maths starter, do a written test and also an interview. Im assuming you have something history related for your presentation but ours was informal, with all the other applicants joining in your lesson.
The written task was about the exeter theory of learning for maths, which you can find on their website, so maybe see if they have a publication on their website about their learning theory for history in primary schools.
Then the interview started with a few maths questions, then more general questions such as what makes a good teacher? why maths? and if there was anything else I didnt have a chance to say in my application.
Hope that helps, I got offered a place so will be in Exeter this September!
Good Luck!
