My course, chemical engineering, encompasses all my main academic interests: maths, physics, and chemistry, with both some pure aspects of the sciences and a heavy focus on an engineering style approach to problem solving.
I would have liked to know that the interviewers really didn't care how much stuff I knew, they were just interested in seeing how my brain worked and responded to problems and new information. There was no need to panic about forgetting the periodic table or messing up some basic maths!
I split my time outside of academics between target rifle shooting and jiu jitsu. I have been shooting for eight years and I have represented the university in two Varsity matches and the universities league. It's a great and time consuming sport but I tried jiu jitsu last year when I arrived at university, and loved it, so carried on with it as it provides a nice balance to my week.
As well as helping with interviews and entrance tests, I also have experience tutoring A level students.
