Read the following passage and choose the most likely answer to each of the following questions.
Normally a student must attend a certain number of courses in order to graduate, and each course which he attends gives him a credit. which he may count towards a degree. In many American universities the total work for a degree consists of thirty-six courses each lasting for one semester .A typical course consists of three classes per week for fifteen weeks; while attending a university a student will probably attend four or five courses during each semester. Normally a student would expect to take four years attending two semesters each year. It is possible to spread the period of work for the degree over a longer period. It is also possible for a student to move between one university and another during his degree course, though this is not in fact done as a regular practice.
For every course that he follows a student is given a grade, which is recorded, and therecord is available for the student to show to prospective employers. All this imposes a constant pressure and strain of work, but in spite of this some students still find time for participation in student affairs. Elections to positions in student organizations arouse much enthusiasm. Students who advise the academic authorities usually perform the effective work of maintaining discipline. Any student who is thought to have broken the rules, for example, by cheating has to appear before a student court. With the enormous numbers of students, the operation of the system does involve a certain amount of activity. A student who has held one of these positions of authority is much respected and it will be of benefit to him later in his career.
