Student-centred learning methods and appropriate media, such as video, text, audio and computer packages are used. Few courses impose entrance qualifications. As a method of learning, open or distance learning can be lonely and hard, requiring a great deal of self-discipline. Open and distance learning courses are usually a way of getting qualifications, whereas learning packages are usually designed for retraining or updating skills. Prices vary greatly, depending on whether for a package or a course, and therefore how much tutorial support is included.
Students can send for several prospectuses and compare prices.
