I don't know what a post graduate degree is...here we do a bachelors of science in college and then straight to the phd also if you fail out of the phd you walk away with a masters...

Is vitro stained glass? No I haven't done it but a friend and her husband do it...right now they don't have the space to do it though. I do love glass but I think I'd rather learn blown glass tbh.

Well I hope it all works out for you whatever you choose...
