well for our year we needed to bring an object that meant alot to us and we had to explain why. Then they asked normal questions like what you want to do, why you want to do them, plans post-16 etc. But personaly it really did feel like a normal conversation and I know alot of people feel the same. Just make sure you show your determination. They also asked us something about the school motto but I cant really remember. It was all in an email they sent us before the day so make sure to check your inbox!!
