Extracurricular activities (ECs) and letters of recommendation (LORs).
In other words; vet experience, life experience, etc.
Honestly, I think it'd be a long shot to get in as an out-of-state applicant with a 3.2 - TN is a great school, and tuition will be MUCH cheaper...which you will appreciate later (if you are taking out loans).
EDIT - even as an in-state applicant it won't be a cake-walk... but can be done. Any reason why you want to go to MS over TN? (Just curious)
