I had to take a year off at one point in a three year degree, so finished in four. At that point I was undiagnosed, but obviously not firing on all cylinders as far at the department was concerned. I got a very good degree, but they refused to give me an academic reference for further studies. My advice... never tell your tutor that you saw the devil playing fiddle outside the market.

In retrospect I don't think it made much difference taking time out. My last year felt odd because all my friends had left. And I was on track to get a good degree anyway, even though I believed in aliens tracking me and all that junk. I think it just gave the tutors a chance to ignore me for a year. I don't think they'd have minded if I'd dropped out completely. It seemed to have shocked them when I did well.
