One more week and I am done with my German 1, can't wait to enroll for German 2. Duolingo helped me a lot.
In case you want to be corrected, otherwise just ignore me:
Noch zwölf Tage und dann werde ich mit Deutsch 3 anfangen. Ich finde, dass Deutsch schwierig ist.
(We don't use the construct [period of time] + more in German. The an- of anfangen doesn't go anywhere, because the sentence has a Hilfsverb (werden)... assuming that's what's meant by 'will'.)
