They are expensive £5400 a year to study full time 120 credits, although most students do part time 60 credits £2700. You can of course fund it with a loan from Student FinanceI've been thinking about the OU for a long time, although they seem to have got expensive in the last few years. Just to study something I'm interested in, I already have a degree from a conventional university which is relevant to my work.
My main problem is time, I can barely manage a handful of hours to do homework / study for my evening Italian class, where I'd find the 15 or so hours needed for a degree course I don't know.
