Hi, Word power made easy will have very limited use. I would suggest you start reading English novels (not chetan bhagat types), watch English news, read English newspapers, etc. Whatever article you read in a newspaper, make it a point to write its summary without seeing the article again and then compare with the original article to see the points you have left out. This exercise is very good for RC. For grammar, you may refer to Wren and Martin and Dictionary of common errors.
