Hope U R Fine By God's Grace, Well I Think Most Appropriate Way To Improve English And It's Expression Is, By Daily Reading Some Good English News Paper Like ;"dawn" Or "the News",very Carefully.and Try To Re-write The Articles/ News In Ur Own Words.this Will Not Only Help U In Improving English, But Also In Current Affairs And Essay Subjects.always Consult Dictionary Immediately After Reading Some Difficult Word And Remember It(do The Same While Reading All The Books For Preparation).further For Grammar ,u Should Consult Any Good Basic Grammar Book.and One More Thing Try To Watch Bbc And Cnn News Channels,and After Listening To Some Discussion Or News ,again Immediately Write It Down On Paper In Ur Own Words.hope It Will Help U To Some Extent Friend.
Take Care,
