Critical care nurses generally work in places such as intensive care units or burn centers. They provide assistance to patients with life-threatening illnesses or conditions such as surgery or serious infections. Students interested in critical care might take courses such as physiology, chemistry, and microbiology.

Students can select individual courses in accordance with their interests. Students may also structure a series of classes in a way that might achieve specific objectives such as improving job skills, pursuing new careers, or obtaining certificates or degrees.

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