Sit down with the degree requirements for the various major programs, and with the specific coursework offered by each institution. Yes, I know that means digging through the websites and the course catalogues, but you have someone who is transferring for a specific major. That makes the process much more like choosing a grad school. Smallfry needs to really look at the details. It is entirely possible that the Earth Science program at UVA is stronger for Smallfry’s specific academic interests than any of the Geology programs. Of if not stronger, at least so close to being equivalent that the in-state discount means underpaid summer internships or slightly pricey field programs are much more possible.
And of course given the pandemic, both you and Smallfry need to be prepared to have at least part of the fall semester spent at home. That’s just the way everything is looking right now. For many families it has changed college plans.
