Oxford - the University Town
Oxford as the university town is very beautiful. The oldest university there is
Oxford. The first of its colleges was founded in 1249. The university now has
thirty-nine colleges and over sixteen and a half thousand students. Almost a quarter
of these students are from overseas. More than 130 nationalities are represented
among our student body. Almost 5,000 students are engaged in postgraduate work.
Of these, around 3,000 are working in the arts and humanities. Every year more
than 16,500 people take part in courses offered by the University's Department for
Continuing Education.
In the years since the war, Oxford has added to its humanistic core a major new
research capacity in the natural and applied sciences, including medicine.
There were no women at Oxford until 1878, when the first women's college
Lady Margaret Hall was opened. From 1878, academic halls were established for
women, who became members of the University in 1920. Since 1974, all but one
of Oxford's 39 colleges have changed their statutes to admit both men and women.
St Hilda's remains the only women's college. It is not easy to get a place at Oxford
University to study for a degree.
The University offers a wide range of taught graduate courses and research
degrees, ranging from one to three or more years in length. While the Master of
Studies (MSt) degree is awarded after examination at the end of three terms' work,
three or more years are normally required to complete a thesis for the degree of
Doctor of Philosophy. For all diplomas and degrees, except the few offered as parttime
courses, students must spend a period in residence - which means
postgraduate students live in term time within 25 miles of Oxford. There are no
external degrees and there are only a few part-time courses in specific subjects.
The academic year runs from October to September and is divided into three
terms and three vacations.
Outside the university there are also many smaller private colleges which offer
less difficult courses and where it is easy to enroll. Most students in these private
schools take business, secretarial or English language courses.
Oxford is, of course, famous for its first-class education as well as its beautiful
buildings. Some of the most intelligent men and women in the country live and
work here. Oxford gives them what they need: a quiet atmosphere, friendly
colleagues and the four-hundred-year-old library, which has about five million
books.
Oxford has some of the finest architecture in Britain. Some of their colleges,
chapels and libraries are three, four and even five hundred years old, and are full of
books and precious paintings. You can see there many lovely gardens, where the
students can read and relax in the summer months.
Throughout its history, Oxford has produced gifted men and women in every
sphere of human endeavor who have studied or taught at the University. Among
these are 5 kings, 40 Nobel prize-winners, 25 British Prime Ministers, 9 current
holders of the Order of Merit, plus 3 Saints, 85 Archbishops and 18 Cardinals.
