10 ways to improve your communication

1) Listen others speech and understand it then try to give reply to them .This may help you to improve vocabulary, grammatical knowledge and accent.

2) Record your voice when you speak English. After you are finished recording, play it back and see what you sound like. If you are not clear, then you can simply try again. This is a great way to see how others hear you.

3) Build trust. Don't say what you don't mean. Don't promise what you won't or can't
fulfill. Follow through with any commitments you make.

4) If you hear a new word and you don't know the meaning, write it down and do research on what it means. In your research you'll encounter many more English words for you to ponder over.

5) Listen to you-Pay attention to what you are hearing from yourself. Does your body
tighten up about certain issues? Body language is not something to read only in other people.

6) Go to your library and pick out titles that are written in English. Try to read those titles. Just be mindful of the difficulty level and even practice writing some of the sentences.

7) Online ESL courses help you to learn English language and provide you materials to learn. All of the other steps can be used outside of your courses to make you proficient in the language.

8) You can seek the help of internet to improve your skill. It is packed full of resources, reading materials, sound recordings, and so much more that can help you learn the meaning of the words that you read and speak.

9) Practice with a friend. This friend may not know English, but impress them with your skills.
You may even try to teach what you have learned because you will be less likely to forget by repeating the information to another.

10) Set goals- Decide how many hours you want to study, how many words you want to learn or what score you want to get in a test are all good ways of making sure you do extra study.
