I've noticed that when using man it can become extremely repetitive
Wenn man solche Goethe-Institut-Prüfungen machen will, muss man bereits wissen, auf welcher Stufe man ist.
Das klingt für mich grausam. Also, my teacher told me Germans don't like repetitiveness in writing. We had to make a Bewerbungspaket and in my cover letter I used Erfahrung/en 3 times and she took off a point or two, because she said you shouldn't use the same word more than once. I know that you aren't supposed to replace man with er so does that repetitiveness not matter for man?
