Yeh it's kinda complicated I don't really know that much about it. On the link i gave it shows that 96 raw = 96 UMS, then from there its a sliding scale downwards where for example 84 raw does not equal 84 ums, more like 70 something ums. then this gap beteen raw and ums just gets bigger the lower we go. Basically all it means is that the more raw marks on the written paper you get, the less you are penalised for UMS down scaling, if ya get what i mean? it punishes those who just do coursework and then relax.
But t around 90/120 raw you can safely assume that it equals 90/120 ums. Anything above that will just get scaled up further in your advantage. I think.
Good luck on friday btw, we need to meet our offers
