Newspaper reading is equally vital part of preparation, you can start with any newspaper like The Hindu, or Indian Express on a regular basis to be updated as well as gaining knowledge which shall be highly useful to you in future exam preparation part. Put a more emphasis on editorial part, it will not only broaden your perspective but help a lot in answer writing,and make sure whatever opinion you form it should be well balanced. You can also make notes of this,it'll be very useful in answer writing.
