Read the following passage carefully and answer the questions, from question 37 to question 40

Students working for their first degree at a university are called undergraduates. When they take their degree we say they graduate, and then they are called graduates. If they continue studying at university after they have graduated, they are called post- graduates. Full time university students spend all their free time studying. They have no other employment. Their course usually lasts for three or four years. Medical students have to follow a course lasting for six or seven years. Then they graduate as doctors. In Britain, full–time university students have three terms of about ten weeks in each year. During these terms they go to lectures or they study by themselves. Many students become members of academic societies and sports clubs and take part in their activities. Between the university terms they have vacations (or holiday periods). Their vacations are long, but of course they can use them to study at home.
