SDN Members don't see this ad. (About Ads) I'm currently a freshmen and I've decided to get my AS degree in nursing and AA degree to major in either zoology or pre-veterinary medicine. I know vet school is the most competitive field to get into. I have a cumulative GPA of a 3.75. Does anyone know what major has a better probability getting accepted into vet school. I know volunteering with animals is a major plus also.
