A student who wishes to treat diseases of the mouth may wish to study dentistry. Dentistry studies how to keep the teeth, gums, and other parts of the mouth healthy and how these parts interact with the body.

A Bachelor of Science is a degree that is often required for certain advanced careers. Depending on how much time students devote to their education, it can take about three to four years to earn a BSc.

Part-time learning allows one to obtain a degree or qualification even if one cannot attend school on a full-time basis. One can learn at one's own pace, gradually accumulating credits that count towards a final qualification.
