    I still don't understand how you calculate your UMS if your graded was an A. The A-boundary conversion just baffles me. Does anyone actually understand how it works? Because by my method of solving things, you'd always need 98.5-100% raw marks to achieve 100% UMS, no matter what the paper was even if it was something like 50/72 for 80 UMS (where the max is 100 UMS). If someone could assist me, cheers.

    I think the point of UMS is that all the grade boundaries are chosen after papers are marked so that however many people they think should get a certain grade get it (roughly). e.g if 10 % of people got over 52 then 52 will be made 80 UMS and that will be an A. I think??

    So it changes for every exam

    Example ... an exam is out of 60 marks and the UMS is out of 100

    Then students take the exam

    If some students score 60 out of 60 the 100 UMS could be set at 60 or maybe 58 or 59
    If the lowest students scored 30 marks then the UMS would be spread between teh 30 and 60



    In an extreme case then best student may have only scored 40 ... in which case 100 UMS could be 39 or 40 marks

    etc
