Thank you so much for your quick response! I'm so happy for you
Also can I ask you did you have a interview about any of your extra curricular activities, if so what did you do/say?
No worries. I did have to an interview, where I was asked how I managed my extra-curricular activities and school work, my current school, etc. Just to mention, everyone who sat the exam had to complete a written response to the school, in which we were asked 3 questions. If I can remember, they were along the lines of; why we wanted to come to the school, our achievements, and what the school values meant to us.
They didn't really ask too much about my extra-curricular activities in the interview, as they already knew from the written response. My main achievement was/is cricket, and they asked me some questions about that. They wanted me to tell them how I planned to progress in cricket, and how to develop it as a possible pathway. They also asked me to explain how I balanced my school life with my extra curricular life.
Just to add for some extra info, they wanted me to tell them something what I liked about my current school, which was quite an interesting question. As I go to a Christian school, I said that I get to learn about a culture different from mine, and understand how other religions and societies differ from mine.
Just a heads up, I recommend not over-practicing for the interview. Reason being that I feel the answers to their questions should be natural and fluent, and not rehearsed and robotic. This makes for a genuine conversation, and not just a process where you're trying to impress the interviewer (you still need to do that btw haha). Also, try to be confident and clear, trying not to sound scared and nervous (you will probs be nervous though, it's natural to be). Try to be a leader in group activities, if you take part in them, but not too bossy and over-shadowing.

Hope this helps, and I'll be more than happy to answer any more questions that you may have.
