As far as expansion is concerned, it is a note, simply read daily dawn news paper. From dawn, point out any editorial which you think that it is an important. Read it twice, after that just write down what you have assumed. In last you will have to check it by yourself. Point out your mistakes. Then overcome your that area where you commit mistakes frequently. That is it. It would not help you out in expansion but also you would be able to attempt your precis effectively.

Thanks.
