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.

Courses are individual classes that can be taken at universities, colleges, junior colleges, and trade schools worldwide. For even greater flexibility, many schools also offer online classes. Students can take individual classes or pursue degree programs.

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.
