I second the Maths degree with the OU. I just finished a masters in maths with them and they really didn't pull any punches. I am a far better mathematician now than I was five years ago (or rather, five years ago I wasn't any kind of mathematician, but now I can blitz through a post-graduate level textbook and bootstrap myself to competency). I'm getting a bit old for serious exams, though. I genuinely started to feel light-headed in the final one.
