UMS Marks Watch
UMS, I assume, is just fitting the marks to a normal distribution curve, then shifting it around so that the right number of people are getting Cs, etc. It usually means your raw mark increases. It's used so that a 90 this year should mean the same as one last year, and a particularly hard paper doesn't mean an abnormal number of fails etc.
also how it is possible to get full UMS points for a module without actually getting full marks on the exam?
It's all about the statistics
