You can develop your communication skills by attending paper presentation contest in the inter-department, intra-department meet that takes place in your college and as well as by attending symposiums and conferences in other colleges.
          And you can take seminars in your class itself to develop your communication and to reduce the stage fear. It is easy for you to speak in front of your friends in your class than speaking in front of unknown people.
          And it’s an efficient and fun way to develop your communication by watching Hollywood films in English language and understanding the story of that whole movie by seeing the subtitles side-by-side. First it will seem to be difficult to watch the movie without understanding the language properly and it will becomes easier when you watch several films. And after you watched 4 to 5 films you can disable the subtitles and watch the same films and try to understand their language as well as pronunciation of each and every words.
