I have stafford loans (subsidized and unsubs) and health professions loans. I didn't need private loans when I was in school.
Your school will likely have some scholarships available. I don't know how they decide who gets them or not because I know a lot of people who didn't get them but that will/may vary depending on the school.
I would also check with your state and see if they have scholarships. That is were I got some nice scholarships and got them each year of vet school as well (I wonder if that was the case because people didn't know about them?).
