Pre-veterinary medicine students can choose a variety of pathways to veterinary school. Some choose biology or chemistry with a concentration in pre-veterinary studies, while others choose clinical and diagnostic sciences with a specialization in pre-clinical professions. However, most veterinary schools do not require a bachelor's degree before admission provided that all the prerequisite courses for the veterinary school have been completed. This concentration represents the minimum course work needed for application to most veterinary schools and provides the background needed before taking the GRE entrance exam. The pre-medical concentration and pre-clinical specialization represent the minimum coursework needed for application to most veterinarian schools. Students interested in pursuing a bachelor's degree must select a major from those offered by the university.
