The rank of your undergrad school does not help you get into vet school. My son’s vet school class has more from lower ranked state U’s with good pre-vet programs than from top rated colleges. The key is low debt, lots of animal and vet hours, ECs showing you can work with people too, high GPA, and if the school requires it, high GRE. The don’t rate top 20 schools any differently that those in the 200s.
Even more than my son’s animal hours they were impressed he volunteered for a hospice and was a camp councellor living with young campers a month at a time, while also teaching them horseback lessons.
Good luck!
