The cost is much below that of attending a resident school. One may enroll at any time. The correspondence method guarantees individual attention. Students are therefore assured of personal individual attention in achieving their aims. This enables the student to understand something of the overall field of study.
Instruction is given mainly or wholly by correspondence.
Consultations can be given by telephone or e-mail in most cases. Each lesson contains direction for study and preparation of the assignments which are to be completed. Students send their work and any queries they may wish to raise to the school. This enables them to plan their own program of study, each of which is worked out individually. This ensures that no student is compelled to cover work already undertaken elsewhere.
