We are from different countries. And the reference frames are different. The teachers are different too. e.g. I usually use CEFR when I think that WSs can be used in different countries. But some WSs are aimed at being used mostly in Russia. where most of the teachers are used to using grades 1-11. Then I mark them in this system. It's hard to say what is better and whether it's possible to have a good solution.
