Frankly speaking, for someone who really obtains a B2 level in a foreign language, they should be able to well express in that language. To this extent, it means that this post should be written in German. Additionally, one should also understand the fact that, to self claim that they have obtained a particular level, and to prove that they did obtain the level by some recognized institution through open examination(s), are two different things. I am not interested in arguments or verbal flames, but when I went through some of your posting in terms of German, e.g., an essay of, https://www.italki.com/notebook/3157987/entry/833370 I have to honestly say that, a person who is really at B2 level, should NOT make the simplest mistake, which is related to the well-known sentence structural rule in German: "The conjugated verb is ALWAYS located at the second position in a principal clause, and is ALWAYS located at the ending position in a subordinate clause." Based on the above rule, I have found at least ten (10) similar mistakes. Obviously, you are still not at the level in which it should be. Naturally, you can claim whatever level you want, but as I mentioned before, to self claim and to prove oneself through recognized institution(s) are different. In conclusion, please kindly keep up the good work regardless all negative comments. Once you have really reached the B2 level, this post would then be more appropriate and applicable. In fact, in European languages, any level that is at B1 or over, it is simply a different world. Do not ever presume that it would be so easy as a piece of cake. Anyway, good luck, and good day.

Ich stimme meinen Vorrednern zu. Nur. weil man ein Buch durcharbeitet, heißt es nicht, dass man ein bestimmtes Niveau tatsächlich erreicht hat. Um C2 zu erreichen, muss man die Sprache täglich anwenden und authentische Texte anhören und lesen, viel mit Muttersprachlern sprechen. Da hilft kein einzelnes Buch und auch kein einzelner Kurs.
