Do you have Canadian citizenship (and should I remember this from a previous thread)?
The main reason that I ask is because of your stated budget. If you are are a Canadian citizen you should be able to get these schools under US$30,000/year. If you are not a Canadian citizen nor permanent resident, (and for McGill assuming that you are not a citizen of France or a small number of other French-speaking countries), then these two Canadian schools will be over your budget.
As an out of state student I do not think that there is any chance that UC Davis will be even remotely close to your budget.
I noticed both a veterinary conference on your list and the application to Purdue and UC Davis, both of which have very good DVM programs. If you are pre-vet, then you want to stick to your budget and try hard to avoid debt for your bachelor’s degree. Getting a DVM is a long and expensive path, and you need to keep the budget in mind to be successful on this path.
Have you run the NPCs for the schools on your list and are they predicted to meet your budget?
Personally with experience in high tech (my career) and veterinary medicine (a daughter’s intended career – she is on-track to get her DVM in a few months) I have a very high opinion of Purdue. With it being in-state for you and with a restricted budget it is likely to be a very good choice. I think that Purdue is a very strong university and a great choice, you will find very good opportunities there, and I see that you are already accepted.
