Cambridge is one of the two main Universities of England located at the
Cam River. It was founded at the beginning of the twelfth century. The
University consists of twenty-four different colleges including four
colleges for women. Each college is self-governing.
The head of University is the chancellor who is elected for lifet The
teachers are commonly called "dons” and “tutors' Part of teaching is
organized by means of lectures. Besides lecture teaching is carried out by
tutorial system for which the Cambridge University is famous all over the
world. This is a system of individual tuition organized by the colleges.
Each student has a tutor who practically guides him through the whole
course of studies. The tutor plans the student's work and once a week the
student goes to his tutor to discuss his work with him. The training course
lasts four years. The academic year is divided into three terms. The
students study natural and technical sciences: law, history, languages,
geography and many other subjects.
After three years of study a student may proceed to a Bachelor's degree,
and later to the degrees of Master or Doctor. Students are required to wear
gowns at lectures, in the University library, in the street in the evening, for
dinners in the colleges and for official visits. All the students must pay for
their education, examinations, books, laboratories, University hostels, the
use of libraries, etc. Very few students get grants.
Not many children from the working class families are able to get higher
education as the cost is high. The cost of education depends upon the
college and speciality.
A number of great men, well-known scientists and writers studied at
Cambridge. Among them are: Erasmus, the great Dutch scholar; Bacon,
the philosopher; Milton and Byron, the poets; Cromwell, the soldier,
Newton and Darwin, the scientists.
