"Formal Halls" are special dinners where students and Fellows eat together. Everyone wears a suit and there is good food. There is a prayer in Latin at the beginning and at the end. These dinners are a tradition and the idea is that people in the college should get to know each other at them. After the exams, there is "May Week" when students make parties. A "May Ball" happens in every college: it lasts all night and there is lots of music and food.
