I’m going to be honest, this one confused me, but I did a little research. This Tweeter wants to know why we use letter grades to mark our work (A-F) instead of number ones (0-10). Apparently, she thinks that numbers are much easier to understand.
Numbers make sense, obviously, but I’m pretty sure letters do too. It would seem that a lot of different countries do grade 0 (lowest) to 10 (highest). England has just started using numbers to grade their exams. So, perhaps we’ll change in the future too.
