번역 - 포르투갈어-독일어 - Tomei conhecimento do comportamento de M.

Schaust du nochmal drüber? Da sind einige Fehler.

u.a. Satzstellung, Grammatik und Wortwahl.

I've tried to... Just reject it if there are still too many errors! How do you say 'German class'?

It depends on the context, it can be Deutschunterricht (at school) or Deutschkurs (language school).

Text before editing:

Ich habe von M.’s Verhalten in Deutschunterricht Kenntnis genommen und er soll die Konsequenzen erfahren.

Can I have a bridge, please?

Here it is:
I knew about M's behaviour in german classes and he'll suffer the consequences.

Hope you understand
