I don't really want to bother anyone here with my opinion about the EU. Ok - maybe I want to a littlebit...
There are comissions that are occupied with the serious duty of standardization of shopping carts and toilet paper (I'm mentioning 2 of the important ones...)
As for the grade thing... If the result of a test is worth a zero, then it's a zero! If that is because someone refused to do the test, or because the pupil had absolutely no idea what the heck has been going on, I don't care. In the first case, he/she knew, what he/she had to face and in the second case, most probably it reflects the amount of work that has been put into learning (ok, maybe that's not the only reason, but I said 'most probably').
If it's been the fault of the teacher (I don't like to hear that very much, because the first excuse I get to hear is exactly this one... when I'm questioning a bit more in detail, the truth is more 'complex'
), then there will be a lot more pupils with a desastrous result. In this case some other measures have to be taken!!!
1)Repeat the test with a better preparation (that means, the teacher has recognized the problem)
2) Use some other sources for your preparation (that means, the teacher refuses to recognize the problem)
3) Remove the teacher (that means the school director recognized the problem)
But according to my experience it's mostly the responsibility of the pupil, and not to 'reward' a certain 'achievement' with the proper grade, won't help anyway - it doesn't help even if it's the teachers fault - so it's absolutely useles in my opinion
