How do you calculate UMS?

I don't know how you calculate it... eg what is the formula?

Help would be appreciated.. thanks

Your UMS should be given on your results slip after being converted from raw marks

edit: I think its calculated using some sort of normal distribution

Well, you wouldn't be able to calculate it without knowing what EVERY other person got on that paper... I think UMS is done by percentile and then renormalised to a linear scale with the A and D grades fixed.

I don't think it's linear

I didn't either but I was 'corrected' and they (teachers...) were quite insistent... If it is linear then surely percentile based would be better?

This is technically what they should have done

Your raw mark / Total raw mark * 100% = Your percentage
Your percentage * Total UMS in that module = Your UMS (after dropping decimals)

e.g. You have got 46 out of 60 marks in a Physics Module with 90 UMS, then
percentage = 46/60 x 100% = 76.67% (2.d.p)
your UMS = 76.67% x 90 = 69 UMS (0.d.p)

Edit:
I don't believe they used anything nonlinear, as using statistical things like normal distribution is unfair for high grade students.

The 'numbers' on the result sheet are UMS. Check the exam board websites to see the raw marks. I used this website: http://umstools.sourceforge.net/demo/www/index.php?p=calculator&target=gce to see how many UMS i needed for the next grade.

UMS is conversion of your raw marks.

This is completely wrong ums and percentages are two completely different things. your formula implies this will work for any grade when really the ums conversion process changes for each exam annually depending on the grade boundaries

Now the forumla is complicated and it wont be of any use to you lool

The ums conversion scale will change for each module depending on the grade boundaries i.e how everyone else performed

If you have the raw marks you can use these websites to calculate your ums mark for each of your modules (for edexel and AQA ONLY):
http://www.edexcel.com/i-am-a/student/results/Pages/Convert-your-marks.aspx
http://www.aqa.org.uk/exams-administration/about-results/uniform-mark-scale/convert-marks-to-ums

and for OCR here is the formula if you want it:
