Hi,here is my review on 30 days to powerful vocabulary by NormanLewis is very useful book to those who want to improve their vocabulary at jet propelled speed.It is a magnum opus by Norman.I am writing review after reading the book. Merits 1.Many exercises are there to make you feel confident about your work. 2.Learning new words by roots makes us to get meanings of many words which share the common root. 3.Tests at end of each session makes the reader to gauge his retention of new words. 4.Useful techniques and the psychological way of dealing with new words. No demerits about the work but paper quality should be better.Go for simon & schuster publishers as goyal is not good.
This book can be used to revise Word Power Made Easy by NormanLewis or as a supplement. If used singly it might not be that much effective as it lacks in volume. I would recommend going through it after completing Word Power Made Easy. It makes the revision much easier and exciting.
