Translation of adelantamiento

So you have taken a German course in the Ghoete Institute. Well, I certainly learned something with you, and your German is already a lot better than last time. I think we really did it.
Yes, but on the other hand, using full, simple sentences also helps people who are learning the language more than just the short clauses. It is probably a mix of both, but I have not decided yet which ratio is the best for us.
Thanks for the corrections and for accepting my friends request. You are completely right: Spanish grammar is simpler than German grammar. I was just looking for a job where both languages are required.
