Oxford University has a Rhodes Scholarship called "Nobel Prize for Global Undergraduate Students". Every year, 80 outstanding senior undergraduates are selected from all over the world to study for master's or doctoral degrees at Oxford University. These Rhodes scholars later had a very important influence all over the world.
There are 39 colleges in Oxford, and their relationship with them is the same as the relationship between the central government and local governments in the United States, which is a form of federalism. Each college is managed by the dean and researchers, who are experts in various academic fields, and most of them have positions in the school.
Among the 39 colleges, Wanling College has no students, only scholars (including visiting scholars). Each college has different scales, but it has less than 500 students, and students and scholars come from different professional disciplines. Oxford's college system was formed when the university was born, and gradually became a collection of independent institutions in Oxford.
