Classes to take in undergrad that would really help you in vet school

While almost none of these subjects are pre-requisites, studying them formally via a college course will certainly help you feel very comfortable with some of the material you'll later cover in the didactic years of vet school. If you have any room in your undergraduate schedule, you'd be doing yourself a favor to take any of these classes. Having prior exposure to these topics will significantly reduce your stress in vet school (I have observed this in my classmates and in myself). Upper-division classes that are intro-level or general are at the appropriate level to groom you for what you'll learn later in vet school (you don't need to take the very advanced upper div courses). You may even consider taking them pass/no pass so they don't affect your GPA but you still get the exposure.
