I would recommend to study the whole course.Make maps with ur answers on paper and show with arrows the advance of belligerent forces.Whenever a general question is asked about any dynasty ;make sure that you make a genealogical chart showing rulers of each generation.
Cram everything but give an extensive study to the subject by studying various books as you are not supposed to rely merely upon K.Ali.Don not forget to remember the month and year of any important event,like war,birth,death or coup etc.
After having completed the course give three revisions atleast.Mind you that the course is lengthy and it is quite time consuming.

And try to learn by heart the quotations for every topic.It is recommended that importation quotations or sayings are compiled in a separate place so that your precious during revision might be saved.
