Some universities have links to others abroad, I hope to do Earth Science next year, I'll be 33, and they have the option to study abroad for a year and list all the universities with degree curriculums close enough to match Glasgow's, if its anything other than and English speaking country, I believe they expect you to be fairly fluent in the local lingo, which makes sense, you can't study if you don't understand the language.
for the US, OZ, NZ and Canada, and possibly even Singapore (Glasgow Uni have a campus in Singapore), then English is enough.
The uni you plan to join will have info regarding the possibility of study a year of your degree abroad on their website.
and even at 33 with a 2 year old, we (me and my Partner) would consider it, would be a great little education for my wee boy also. And my partner should be able to get a transfer abroad with her company for a year.
