Betjeman entered the University of Oxford with difficulty, having failed the mathematics portion of the university's matriculation exam, Responsions. He was, however, admitted as a commoner (i.e. a non-scholarship student) at Magdalen College and entered the newly created School of English Language and Literature. At Oxford, Betjeman made little use of the academic opportunities. His tutor, a young C. S. Lewis, regarded him as an "idle prig" and Betjeman in turn considered Lewis unfriendly, demanding, and uninspiring as a teacher. Betjeman particularly disliked the coursework's emphasis on linguistics, and dedicated most of his time to cultivating his social life and his interest in English ecclesiastical architecture, and to private literary pursuits.
