UMS explained!. What are A-levels worth?. Most A-levels are made up of four units , with a grand total of 400 UMS marks available. Six-unit A-levels are out of 600 UMS marks T wo-unit A-levels are out of 200 UMS marks. The best way to understand UMS is with an example!.

What are A-levels worth? • Most A-levels are made up of four units, with a grand total of 400 UMS marks available. • Six-unit A-levels are out of 600 UMS marks • Two-unit A-levels are out of 200 UMS marks
The best way to understand UMS is with an example! • Let's imagine a four-unit A-level, with the first unit (we'll call it Unit X) worth 30% of the qualification. • There are 400 UMS marks for the whole qualification (because it's a four-unit A-level), • So Unit X will be worth a maximum of 120 UMS marks (30% of 400). Don’t progress to the next slide if you don’t understand this!!
For ALL A-levels… • Grade boundaries for UMS marks are fixed so that:A = 80% of the maximum UMSB = 70%C = 60%D = 50%E = 40%
Lets continue with our example! • For Unit X, this means that our UMS grade boundaries are:A = 96 (80% of 120)B = 84 (70% of 120)C = 72 (60% of 120)D = 60 (50% of 120)E = 48 (40% of 120) UNDERSTOOD? If not go back two slides and start again!
Let's say the Unit X exam is out of 80 marks. • These are called raw marks. • Once the exam has been taken by everyone, a committee at the exam board gathers to decide what the grade boundaries for this particular paper should be • They take into account for example how difficult it is compared to earlier versions of the Unit X exam Are you sure you understand?
Unit X • For this exam, let's say the committee decides that the grade A boundary is 60 out of 80 and the grade E boundary is 36 out of 80 (remember, these are raw marks). • The other grade boundaries are spread evenly between these two points.
We now convert the raw marks to UMS marks, because we know where the equivalent grade boundaries lie… • If you took the exam and got 60/80, this would give you 96 UMS, because 60 happens to be the raw mark grade A boundary set by the committee, and 96 is the uniform mark grade A boundary for this unit. • If you got 55/80, you would get 86 UMS (grade B). • If you got 45/80, you would get 66 UMS (grade D).
Conclusions… • Because the raw marks are converted to UMS marks, it means different students' grades can be compared side by side, with a particular UMS (and ultimately grade) representing the same level of achievement no matter when the unit was taken.
