You have missed out on the Abbasids which is a very important topic considering that Spain and Baghdad were the two citadels of civilization that the empire was considered to have. Caliphs from Al-Mansur to Al-Wathiq and the period they cover along with the grandeur of Baghdad should be aptly prepared. I think the Abbasids have a definite edge over the Turks in terms of the questions that come based on culture and renaissance in the papers.
