Upside Down Grades

Until now in the UK, a 1 or some variation of A has been the highest grade for most exams. The old CSE had 1 as the highest grade, and the highest grade of Degree is a 1st etc.
With the new 9-1 GCSE, the highest grade is a 9. A lot of people will get confused in the middle of the night, dreaming they have all 9’s or 1’s and not knowing whter they are living the dream or having a nightmare.
