The field of medicine concerns itself with diagnosing, preventing, and treating human illnesses and injuries. Medical students learn to heal and care for sick people, using their in-depth knowledge of the human body and topics such as pharmaceuticals and surgery.

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.
