Or whether degree grades are based on relative position within a class at a university or national standards over a number of years?

So nobody knows? Intuitively, if universities base grades on internal standards, there is no point in having a national grade scheme. If the grade is academically meaningless then you might as well have an a1fivestarsuperduper certificate of stupendousness (A1*****SupDup Cert. Stup.) as a BSc 2.1. And why BSc anyway? I am not a batchelor!

oh no! This thread is about to get scrubbed off!

So am I smarter than Stella or wot? Maybe I'll never know........
