I hav came through ur optional mentioned in your profile.. journalism and geography are good but in 2012 sociology was nt a scoring, so i will suggest you to look for options from punjabi, internaitonal law and psychology for your allocation...as fr as preparation is concerned you must focus on your english composition as well as essay, be attached with a teacher of english anyone of renouned. reading of dawn is vital for any css aspirant so please try to focus on pointed areas...be blessed
