Someone from The London Interdisciplinary School ,any interview tips or insights?

Hello everyone ,
I am expecting an interview in a few days .I have kind of a idea of what they wanna see in a candidate and what they are going to check for but I would like to know how was you experience ?What type of questions did they ask you?I see that they included that in the things to have for the interview was a calculator ,is there maths involved?Because the degree is so abroad which I love ,what type of assessment should I expect ?Idk is a lil nerve-racking, I know I have the excitement and hungriness for the degree ,but I am not quite sure or confident about my current skills they are going to test.
