Raw points to UMS points - scaled etc
Have tried to understand conversion of raw to UMS - understand principle but
if the Chem unit 2 paper is out of 60 and you look at aqa boundaries for points/UMS points why out of 90?
i don't get it
any help from scientists and mathematicians - its for AQA Chemistry unit 2
Bascially how many raw points do you need out of 60 to gain maximum mid A* UMS equivalent - i know 90 UMS = A*
thanks

Re: Raw points to UMS points - scaled etc
all very complex - I found the best thing was to ask the kids to explain

I think Chem 2 is the paper CH2HP and is out of 60 .. suspect this is the one that you are looking at?
then to find the UMS for that paper try using this:

it is possible using this to print out the table for all the raw scores and their UMS - note however that no 2 modules are the same...... and can vary from one sitting to another

Re: Raw points to UMS points - scaled etc
Thanks - helpful so 90 UMS is low A*
Thanks for taking time

Re: Raw points to UMS points - scaled etc
Yep 90 is the A* threshold and is equivalent to 44 raw marks
