Thought you'd be interested to know that I've just found out that along with their usual raw/UMS grade boundaries, Edexcel are also releasing conversion graphs for exam results. This is useful to see the CAP, as well as exactly the spread of raw to UMS (instead of trying to have to work out roughly how many raw marks you achieved).
AQA already have this (see spoiler), so I presume Edexcel don't want to be left behind. Presumably it will look something like AQA's.
This will be released the day before results day along with Grade Boundaries. This might not be important to you but I am quite pleased that they are doing this as it always interests me to know exactly how many raw marks I achieved.
