Ok, to cut to the nitty gritty, I seem to recall that the results piece of paper is about as impenetrable as the NorthWest Passage pre global warming. I have just looked at the AQA website which (un)helpfully says:
"Firstly find where your raw mark lies between, and thus your grade. If your mark lies on the grade boundary, then your UMS is just the minimum UMS for the grade (see the tables above). If you got a B, C, D, or E (where the relationship is definitely 'almost linear'), then it's relatively simple to find the UMS:
Work out the gap between your grade's boundary and the boundary of the grade above in raw marks;
Work out 10% of the total UMS marks (which is the gap between your grade's upper and lower boundaries in UMS marks);
Work out the gap between your raw mark and your grade's boundary below, in raw marks (which is how far you are into your grade in raw marks);
Divide the number worked out in step 3 by the number worked out in step 1;
Multiply this number in step 4 by the number in step 2 (which gives you how far you are into your grade in UMS marks);
Add this to your grade's UMS boundary, then round to the nearest whole number if appropriate, to give your UMS score.
A worked example should make things clear. Let's take AQA A Psychology, PYA1, summer 2006 session, and we see that the examiners have concluded that a particular script has gained 32 overall in raw marks. From the grade boundaries:
Grade Max. mark A B C D E
Scaled Boundary Mark 62 39 33 27 22 17
Uniform Boundary Mark 100 80 70 60 50 40
So 32 is a C; it falls into the linear range. But what UMS score is 32/62 raw marks?
raw gap = B - C = 33 - 27 = 6
UMS gap = 10% of 100 = 10
how far into a C in raw marks = 32 - 27 = 5
5 ÷ 6 = 0.8333...
how far into a C in UMS marks = (5 ÷ 6) × 10 = 8.333...
UMS score = 60 + 8.333... = 68.333...
Hence 32/62 is about 68/100."
Blimey. All this at 8am in the morning whilst panicking. Is that why we need a calculator with us (I had assumed that was to work out if we could afford the fees ;-) )
Am I right to deduce from this that the results sheet has raw marks (that we have to convert to percentages and then find out grade boundaries), or is it just marks out of whatever that we just scale to a % and KNOW that 90% is an A* on the basis that the UMS process has already been applied? I so don't want those 10 minutes of total incomprehension having opened the envelope and can;t find any good guides online. Thank goodness for maths where I know that we are looking for scores of 90/100 in each of C3 and C4 so at least I will understand it...
