A Master of Science or MSc is a postgraduate degree typically in the fields of sciences and social sciences. MSc may be course-based, research-based, or a mixture of the two.

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.
