Easier–they do not have to flunk out students to lower numbers to operate within chartered limits, competition is not as intense.

It is a good way to find out if the intended study program suits the student, maybe he(she) is not really happy or capable of studying at the college level.

Diversity–many fields of study may be investigated.

These colleges are a convenient way to get credits needed to matriculate at state colleges /universities at reasonable cost, easier pace than while concentrating on your major subjects in subsequent years.

My personal use was to take a 10 credit hour physics course away from campus where I knew I would have trouble with that prof, and later to take courses to fill in for specific job activities.
