Who can tell me

This is important for learning language:

You must use your learning(vocabulary,sentences,grammar...). And for this, you must talk& write . I need this too. If you want to study with me, write to me.OK? You can share your knowledge with me & I want to this.

See you ;)

l think you had better study it in four parts: grammar, reading, writing, and listening. of course you must begin with improving your grammar skills, then it will be easy to go on to the other levels. either you buy a good book or find a good site along with ebaby, once you practice it regularly in a full discipline, then you can achieve anything on this branch.
