You should check on Purdue. They have a program (new this year?) where you apply as a senior in HS, then do 3 years of undergrad, then start vet school in the 4th year. So graduate in 7 years total. It is for “high achieving seniors”–seems to me your D would qualify. I don’t know about cost, although Purdue is a place that does give merit money to out of state kids.
