Do what you love
One of the many myths about Oxford is that there is no time to have fun. Alongside your college community you will be able to develop your interests, old or new, through over 400 clubs and societies, many of them University-wide.
Taking part in extra-curricular activities is not only lots of fun and great for your social life but will help you build skills which will stand you in good stead for the rest of your life and help with your career goals.
