I have hesitated to post this here, since the problem itself is not really worldshaking important, however I think it has to be adressed.
In Berlin it is so that orthographic and other linguistic mistakes in math tests are counted as mistakes like math mistakes. This means that your math could be flawless but your grade could nonetheless be less good, because of language mistakes.
