It is important to thoroughly familiarize yourself with the customs and culture that make Oxford unique - from their three 8-week terms, Michaelmas, Hilary, and Trinity, to the three holidays between each term, Christmas vacation, Easter vacation and the long summer vacation. Research how new students are called Freshers, how they are expected to leave campus during the holidays for balance and sustainability, and other relevant aspects of their culture that relate to the structure of their terms and campus life. This isn't solely to showcase you came to this interview prepared and know what to expect. You want to convey that you are adaptable and look forward to all that a life attending Oxford offers.
