I went to a very small private school from kindergarten through sixth grade. Then I attended a very large private school from seventh grade through high school. Most recently I have attended two different public universities. I don't know whether I will attend a public or private veterinary school. In all honesty, I'll be happy to get in to any veterinary school!
If I have kids and if our family lives in Hawaii I think I will send my kids to a private school. Hawaii has a rather poor public school system.
