有咩ｃｏｕｒｓｅ可以提昇ｗｒｉｔｉｎｇ　ｓｋｉｌｌ？

我都好同意呀,因為如果冇人話俾你知岩定錯,你根本好難改善到D英文~我而家係englishtown讀緊,我覺得ok,佢個course就冇話齋練writing既,樣樣都有D,不過我覺得oral好左,都幫到自己writing個方面~如果你話想針對grammar個D佢online有個grammar lab,可以學番D grammar,亦都有片睇,但我覺得咁樣同你睇英文書分別唔大,齋學唔練都係死~所以佢個度都要你作文,老師會係兩日之內改番篇文俾你,呢個都幾好,因為真係知自己錯咩~同埋你可以任練,只要你肯寫就有人同你改
另外佢oral個part都學到幾多野,因為除左online,仲要去centre上堂,同埋有課外活動參加,我最常去佢個pronunciation workshop,可以改善番自己d發音,而課外活動就識勁多vocab,因為真係勁去唔同活動,你會識到勁多唔同既生字,譬如我地會去玩wakeboard,打golf,船河等等...
至於British Council我唔知佢有冇writing既course呀,但我而家個度有D同學都去過BC讀,但話上堂既模式都係同U差唔多...作用不大,好睇同咩人一班,有時都幾悶

im not really sure is there any suitable course in hk!!!but i think if u read more english books speak more and check any words in the dictionary that you dont understand,i think that would help!!!im my opinion i think speak more english would help the most!!!!

hope that my advices would be helpful to you!!!!:)

but the main problem,no one can teach me, and no one can criticize me, no one can point out my problem, I won't improve even I write a thousand of composition

There is actually no specific course for your writing.
If you write more and practise it daily, then your writing will naturally improve.
At this time, people would normally say, " Practise makes perfect" and " No pain no gain".
