to be added
A university student was an individual who studied at a university.
Unlike school and college students, university students usually studied just one subject. They were often referred to as a student of their chosen subject, for example both Liz Shaw (TV: Spearhead from Space) and Martha Jones studied medicine and were therefore referred to as "medical students". (TV: Smith and Jones)
A student in their first year of university could be referred to as a fresher. (TV: Knock Knock) A student who completed university was known as graduate of that university. (AUDIO: Autumn, TV: Death in Heaven)
Time Lord students
The Deca were a group of top-ranked students at the Time Lord Academy. (PROSE: Divided Loyalties) The Doctor was one of them, even though he did not excel academically, graduating only with a 51% pass rate on the second attempt. Romana, however, achieved a "Triple First" when she was at the Academy centuries later. (TV: The Ribos Operation)
