Translation of siebenhunderteins

Grammar exercises give the teachers and the students different ideas. We discussed the need for exercises in my previous email, but unfortunately I did not receive any further feedback since then.
Therefore we use only the Vocabulix dictionary in our class. It has good features and a large vocabulary base. I will have to send you a few sentences for rewriting if that is OK with you, because the whole is mixed up.
Now I am learning by other means, such as reading and writing. I can not begin with conjugation training because I lack the basic knowledge. How are you learning at this site and which is your best lesson?
