Does Oxbridge care about extra-curriculars, like sport, in your personal statement?

It's not that Oxbridge doesn't care about extra-curriculars per se, but that they focus more on your academic interests and your passion for the course you're applying for. What they like to see is evidence of super-curriculars, or activities you do in your own time that relate to your degree. For example, volunteering at your local history museum and applying for history. This doesn't mean that you should erase your time playing netball or football! All of which are things you should include and be proud of. Remember that Oxbridge only take up one out of five places in your application, so a statement can't be entirely tailored towards Oxford or Cambridge.

A good way of including extra-curriculars is by integrating them with your interest in your course. Did being part of the Amnesty International society in secondary school change the way you approached history for example? Did playing sport make you think more about the physical effects on the body and science etc.? This is a way to not only help the flow of your statement but to highlight how your passion for your subject is something that you regularly apply and pursue.
