'Affiliated Student' is the term applied to a graduate with an approved degree from another University, who is studying for a Cambridge BA course. (In particular cases, students without a previous degree but with substantial experience of higher or adult education may also be admitted.) Affiliated Students in Classics normally take the degree in two years by studying for Part 2 of the Classical Tripos. Sometimes such a student may be allowed to take a one-year Part 2 course.
You will need to apply to a particular College, so you are recommended to make informal contact with that College first to ensure that they accept affiliated students in Classics. You will then need to submit a UCAS application and, if you are living or studying in a country outside of the EU at the time of application, a Cambridge Online Preliminary Application. For details of application procedures, deadlines, and information about the various Colleges, please see the University’s Undergraduate Study website: http://www.study.cam.ac.uk/undergraduate/access/mature/affiliated.html
Part 2 of the Classical Tripos consists of a wide range of in-depth papers in the various areas of Classics. There is also the option of offering a thesis in place of one of the papers. For the regulations and current syllabus please see the Faculty’s Undergraduate handbook. Because of the great degree of choice available in tailoring the course to individual requirements, the Cambridge Classics Part 2 is suitable for students from a wide range of previous degree courses. It is possible to choose papers that require a knowledge of both Greek and Latin, or of just one language, or of neither. (The papers in Ancient History, Archaeology, and 'Interdisciplinary' approaches do not in general presuppose knowledge of the ancient languages.)
Training in basic language skills does not form a part of the examined Part 2 course, but opportunities for the study of Greek and Latin are available both in the University and in the Colleges.
