The UK’s percentage scale is unfair and fuels grade inflation

I do not buy the arguments in this article. In my career, I have awarded marks in the 80s a few times and never ones in the 90s (except in straightforward first-year exercises, for example). There have been one or two students in the 1000s that have passed through, who achieved an overall average of over 90 but they are very rare. I know of colleagues who have given dissertation marks of over 90 but the work has then been published in a top journal. So, no grade inflation occurs from the exceptional, brilliant students and the rest of the scale puts students in a reasonable order, which is its function.
