London has the largest student population of any British city, although not the highest per capita. Universities in London may be divided into two groups:
First, the federal University of London, which, with over 120,000 students, is the largest contact teaching university in the United Kingdom (smaller only than the distance-education Open University) and one of the largest Universities in Europe. It comprises 19 colleges and 12 institutes, as well as a distance-learning External System. Constituent colleges have a high degree of autonomy, controlling their own admissions and degree programmes, and are effectively universities in their own right. The largest and most well-known University of London colleges include (in order of size) University College London, Birkbeck, King's College London, Queen Mary, the London School of Economics and Political Science, Royal Holloway, Goldsmiths, and the Institute of Education. Smaller schools and institutes (with fewer than 5,000 students) include the School of Oriental and African Studies, the London Business School, the School of Pharmacy, the London School of Hygiene and Tropical Medicine, St. George's Hospital Medical School and Central School of Speech and Drama. Traditionally all of the University of London institutions awarded degrees from the University of London itself, and not from the individual college or institution, but this changed in 2007/2008 when University College London, King's College London, the London School of Economics, and the Institute of Education remained within the University of London system, but began awarding their own degrees. Imperial College London was a part of the University of London until 2007, but is now a separate institution.
Secondly, there are other universities not part of the University of London, most of which were polytechnics until UK polytechnics were granted university status by a 1992 Act of Parliament. Among these are London South Bank
