Coursework raw marks to UMS conversion
OCR Computing AS and A Level Discussion Board: 2510 - Computing Project: Coursework raw marks to UMS conversion
Hi, I know this kind of thing changes on a yearly basis for some exams/coursework, but some people must have a fair good indication on this process.
Is the conversion usually 1:1? (ie. 60/120 raw marks = 60/120 UMS)? If not, which way does it tend to swing?
I have a feeling, because the coursework isn't a set of questions which may vary in hardness, that the mapping is set, but I'm not too sure what this mapping'll be. The fact both are out of 120 suggests to me it'll be 1:1 for the sake of being easier.
I ask because I've done all these calculations - what i'll need to get in 2509 and 2511 to get an overall B - but I've based this on my coursework's raw marks.
The purpose of UMS is not just to maintain consistency between sessions (i.e. from year to year) but also to maintain consistency between modules. (An A in 2510 should be of the same standard as an A in 2509 or 2511)
So although the 2510 paper does not vary from year to year, a certain amount of scaling is still necessary to ensure that all modules are of the same standard.
I do agree that in principle, this means that the same scaling should be applied from session to session, so the scaling used in previous sessions should still apply.
This scaling (previous sessions) is publically available although I do not have it to hand atm. You can ask your teacher... it is in the examiners; report of any of the previous sessions. This information will give you the grade boundaries in raw marks for each of the grades and you can use this to estimate your UMS mark from your raw mark. If you wanted to calculate your exact UMS mark then (assuming that the scaling is the same) you will need the A and E boundaries as well as an understanding of how UMS scaling works. There is a good explanation on Ed-Excel's website at http://www.edexcel.org.uk/VirtualContent/59451/UMS_Awarding_modular_GCE_C2000_qualifications.pdf.
Good luck with your written modules.
thanks for the response. the ocr website seems to very bad for this kind of information, unless i'm looking in the wrong places. aqa and edexcel seem to be good, but i can't find examiners reports or anything on the ocr website.
