Honestly transferring vet schools is extremely rare as they have a different curriculum and obviously they need to ensure you cover everything. If you did transfer you’d more than likely have to start again in first year, and may still have to pass interviews etc. But that being said, if you have extenuating circumstances by all means drop Liverpool an email. Unfortunately if it’s a case of “I’d just feel happier there” it’s really unlikely, but there is a student from Edinburgh uni that has actually transferred to Liverpool in third year to our third year, so it’s not completely impossible but I don’t know their personal circumstances.
