All sciences are interested in the understanding of the universe and humanity’s place in it; however, natural science is usually focused on helping students understand, through observation and experimentation, how energy and matter combine to affect the physical world.

In order to improve job prospects and learn more specialized information, many students decide to earn an undergraduate degree, such as a Bachelor of Arts. Certain schools allow students to earn a BA on a flexible schedule through online or part-time programs.

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.
