You do different types of work depending on your subject. Reading and writing, practical work, lectures and seminars, projects these are some of the ways in which university students learn. The main thing to remember is that universities want you to do well, and will do all they can to help you. This is your chance to study the subject you are really interested in. You can choose from a huge range of courses to fit your interests.
Universities suit their teaching to the subject.
Each course and each university will have quite different ways of doing things and you should decide what appeals to you. At lectures, a tutor or lecturer explains ideas to a large group of students, who listen and take notes. Students take part in discussions when they go to seminars. Some courses have practical work in laboratories, workshops or studios. Sometimes you work together in small groups of students.
