Hello
As for whether or not I learned this, I just read an academic report by the inspection services intended for its ministry or the government, I can't remember, 2013, it’s impressive, even the grades, many don't know what they are nor do their parents, out of 20 it's very French sometimes reserved for baccalaureate exams.
People are trying to convert greens, blues, reds, and A B C D into grades, assignments already weighted by the fact that they are all out of 6, out of 18, out of 3, acquired skills to review, not acquired.

It’s no longer just a question of averages and they complain that we don't respect enough the instruction to abandon numerical grading in certain areas; if you read, you can find such things for a few decades, in the midst of everything else.
It almost seems that every subject, even those of national curricula, everyone talks about and seems to know, but you definitely shouldn't go verify if everyone followed along; in some places, you can read this too, amid everything else. It's also very French.
And on top of that, when you change countries, the curricula are no longer the same.
