My 11 year-old son's story writing has improved tremendously with the aid of the Tutor Master book. It helps structure his thoughts before putting pen to paper and his stories have really progressed in just a few months. I can reccomend this book as a very good aid to good story writing.
My wife already had good English but since using this book I have noticed a big improvement in her comprehension when with friends and her everyday vocabulary is much more natural. This is a great book if you want to really improve your everday English.
