bored of sc said:So does this mean a mark of say 95 could be scaled up to 100? This doesn't seem right as 100 is a "perfect" score.
If 95 was the top raw mark then yes (and that has always been the case) but it is more likely that 95 would go to 96 or 97.
100 would stay the same with 99 probably also raising to 100, 98 to 99, 97 to either 98 or possibly 99 depending on how low the actual cut-off was and therefore how many marks have to be in the range. What I mean is if the Band 5/6 cut off is set at 86 then all the marks 86 - 100 have to be put in the range from 90 - 100 meaning some marks would rise by 1 mark to allow for the extra 4 marks into the range but if the cut-off was say 83 then some marks would have to go up by two marks to allow for the extra 7 marks that have to be fitted into the 90 - 100 range.
Is that clear (or as clear as mud)?
