I can't speak for either veterinary schools, but I stumbled upon this question so I'll throw out some thoughts I have. I do attend undergrad at Ohio State and I know that the vet school here is moving in the direction of taking mental health very seriously. From what I hear from advisors and faculty connected to the vet school, after a suicide in 2015 of a OSU vet student they have really been taking the time to focus on mental health. Switching to IS tuition is definitely doable, but I have heard to just keep in mind that they watch you (or your bank account) like a hawk! At the same time, I know someone going to Cornell over OSU. Also consider the city of Columbus. I love being at OSU and also having downtown five minutes away to do some fun things! I'm really exhausted so please ignore if any of my sentences didn't make any sense! Good luck with you decision - they are both fantastic schools!
