My tip is to listen to very much German music and get the texts from the song to sing or read it. You so also learn the spelling an intonation of the words. There are many singers and groups who sing well spelled. Much fun then with German music learning. Reading German books also is ueseful.

There are no shortcuts for language lerning. German is not a easy language to master. From my perspective, the best way to enhance German level is to recite more, listen more and speak more. Only in this way can you overcome the complicated German grammar.

I'm trying to learn German as I'm beginner ,but I have an idea; 1st we must study the subject pronouns well. 2nd study the verbs forms with each. 3rd study some verbs and words. 4th study other grammars like past ...... good luck
