The Open University is a distance-learning institution - students do not come to a central campus but study from where they live or work. Course materials are delivered to the student and consist of specially prepared texts and audio-visual materials. In addition, an increasing number of courses require the student to have a computer with access to electronic communications. For each course a student has course tutor who offers tutorials, telephone contact and who marks and comments on student work.
