scoring 100% on it is so much easier than scoring an A*/9 on GCSE Additional Mathematics, to the extent where this gap in level of difficulty is equivalent to the difference in difficulty between:
- scoring an A*/9 on GCSE Additional Mathematics
and
- scoring a perfect 42/42 score (not just a gold medal) on the International Mathematical Olympiad exam
I.e. the jump in mathematical ability from scoring 100% on a hypothetical math exam 'X' to scoring an A*/9 on GCSE Additional Mathematics is equally as profound as the jump in mathematical ability from scoring an A*/9 in GCSE Additional Mathematics to scoring a 42/42 (not just gold medal) on the IMO exam.
How easy would 'X' have to be for this to hold true?
