As a natural segue topic for many degrees, the study of human rights can provide a broad understanding of the issues and current moral dilemmas surrounding the proper treatment of people. This area of study may be ideal for law, education, business, or government students.

The PhD is a doctoral degree, specifically called a "doctor of philosophy" degree. This is misleading because PhD holders are not necessarily philosophers (unless they earned their degree in philosophy!). That said, PhD recipients are able to engage in thought experiments, reason about problems, and solve problems in sophisticated ways.

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.
