Because I'm.. not young.. all throughout my education we were 'awarded' 4 points for an A, 3 for B and so forth to calculate Grade Point Average (GPA.)

Due to this system I have always considered A > B > C, etc.

Some of my children lived under a different regime in elementary school, which common core and non-letter grading assessments. Target, Near Target and Below Target.

A = 1, B = 2 reminds me of cryptography for some reason. That's probably due to reading Neal Stephenson.
