Q: I read book Quick and Easy Way to Effective Speaking. It gave me practical skills to do my presentation in the right way. I defended my thesis on 29th of December 2010. Some professors said me, that it was interesting speech. The principle of effective learning is read and do as written. Moreover it allow me to raise my language skills in English, because this book is written in understandable way and I am Russian. Many thanks to author and people who produced this book.
