Confused - you will be...

If you replace a grading system which goes from A (highest) to E with one that goes from 1 to 9 it should come as no surprise if some people assume that 1 is highest and 9 lowest.  And yet this is what has happened with GCSE grades.  In fact grade 9 is the highest and grade 1 lowest,   Many employers, and even some Universities apparently fail to understand this.  The expression "If it ain't broke, don't fix it" springs to mind.
