My daughter is enrolled in the medical forum but wants to be a vet. We were told the medical forum is where she should be. Do you really think this will be beneficial for her in deciding if she wants to be a vet?

definitely. I went 2 years ago &wanted to be a vet. while most of the medicine &site visits are geared toward human medicine, our group talked a lot about college &the courses needed for med school, which will be pretty much the same for those needed to be a vet.
the forum could also have the same effect on your daughter that it did on me. I went tehre wanted to be a vet, but shortly after my return, I decided that, because of NYLF &the things I experienced, that i wanted to bea surgeon.
in any case, I would suggest that she definitely go. NYLF/Med was the best experience of my life to date.
