Right, I'm sort of having a 2am panic now and I've looked up all sorts of stuff on the internet. Most sources seem to say something along the lines of
"From the January 2008 examination series, a candidate who wishes to re-use unit scores in an effort to improve a grade is no longer required, nor will be able, to decline the original award. This means that, after certification, candidates will not have to retake the whole qualification to improve performance but may do so through re-sitting individual units. The last date by which candidates can decline a grade will be 20 September 2007."
Does this apply to me if I'll be resitting in Jan 2008, then?
