take a subject and try to finish it within time limit say a month or so.. if you bored up studying one subject daily then combine eg:history&geoegraphy and try to finish it within time span the move on to next... important if you take indian history it is divided into ancient,medival,modern, simlarly geography.... so plan first, select the tough ones to study first and the easy ones later. thereby you can finish the entire syllabus within the stipulated time.
