i think it will best for you ,that more read American newspaper and lesson . hopefully you gain your dream .
Would someone please explain to me what "American" English is? I recognize that expressions vis a vis American,English or Australian are different.But I believe the language is fundamentally the same. My first language is French.In France,Canada,Switzerland,the Carribean,Africa etc.,French has different expressions but is spoken the same way.
If you are familiar to general english grammer then you speak always english every time and you will fill after some days your language is better than before........
