Improve Your Written English 

• Write frequently, in a wide range of formal and informal situations.
• Get the most out of your dictionary by understanding how to use it correctly . You can use a good English dictionary to find words, for meaning, for pronunciation, to check your spelling and to understand explanations.
• Copy out short passages of English text from newspapers, magazines or books.
• Try dictation exercises. You can do this online or get friends to read out text for you to write and then check your writing - concentrate on spelling and punctuation.
• There are many forums on the net, find one about your interests or hobbies. Observe the niceties of forum use , and apologise if you think you have made any mistakes.
• Use a blog to create a diary about your life. Write it in English and if you have a thick skin, ask for feedback. Remember blogs are not private, so do not write anything there which you do not want the whole world to read. I recommend http://www.blogger.com , it is free and very easy to use.
• Be careful about using abbreviations when writing on forums and in chatrooms, they are fun and quick, but can cause bad habits to form.
• If you are using a computer, use an English spell checker (but don't rely on it). There are spell checkers built in for Google and Firefox browsers.
• Check what you've written. Even better, get someone else to proofread what you've written. Check for spelling, capitalisation and punctuation.
