In fact, doesn't board people work out cutoffs for each band using standards packages and other things? Perhaps Linear interpolation is used for marks in between bands, and not for the band cutoffs?
No, it's ok. Like you, I was extremely surprised when I calculated the raw Band E4 cut-off to be 40/120. Hence I was doubting my own calculations. I was just wondering if I'd missed anything obvious. I PMed Laz and apparently on second calculation he ended up with the same result as I did - 40/120.Slide Rule said:No, I cannot see anything wrong with your calculations, Rench. Sorry if I implied that. I just find it hard to believe that the cut-off is anything less than about 70/120.

I have doubts about this linear interpolation too, i remember trying it out for mx1 and it didnt seem to work out.
Yea, it sounds odd. As for linear interpolation...there's no other real way to calculate aligned marks given that the BOS Committee only establishes raw band cut-offs and nothing in between. Cut-offs are determined for each Band and then marks are linearly interpolated between each band cut-off.underthebridge said:In fact, doesn't board people work out cutoffs for each band using standards packages and other things?
