Well I think it was about £37 to hire the cap and gown for the day, and I suppose you don't have to buy anything like photo's, but I'll probably be getting some of the above shot for about £25 - it's probably only going to be this once I do it, so I don't really mind. Maybe one day (in quite a few years) I might go back and do a masters or something, but no specific plans as of yet.
