Online courses at university level have become increasingly popular, especially for courses that are limited in the number of entrants, institutions which have limited resources to conduct successful teaching of all subjects on site, and by students residing in regions far away from the university premises.
The added benefit is that a wide range of interesting new courses are being offered ranging from arts to science subjects. In fact, recent software developments have enabled one university to conduct virtual lab experiments from their laptops, removing the obstacle of having costly laboratory facilities onsite and enabling more students to conduct experiments without being limited by equipment availability.
Online courses have also been useful for people of all ages to learn more about a subject of interest. Furthermore, part-time online courses have been found useful for people working full-time and are seeking to re-train for an alternative career.
