What is the hardest part of German?

Hello, some people consider grammar the hardest part of German. Others find listening or speaking more difficult. In my opinion, every part becomes difficult if German is not learned systematically from the roots. That is why in GermanPerman course packages we teach the language from the basics, not only in grammar but also in reading and listening. Memorizing does not help. Understanding the language makes it last.
Thank you

Hello, in my opinion the hardest part of German is the beginning, because everything feels new and unfamiliar. You have to get through the first two weeks until you get a little used to the language. The teacher’s packages make this start easier. Join in and share your opinion. I would be happy to know.
Thanks, Papi
