I am a freshman in a very intense AP World History Class.  Anyways, our teacher rescheduled an essay to tomorrow instead of Monday, and we had 2 days to study for it, today included.  There could be three possible topics, and two weren't clearly defined and we haven't studied them completely.  I am trying to find 3 more coninuities and three more changes for both of the following:
Islam's Inception to Turks
and
Classical Europe to Early Middle Ages ca 1000 C.E. (which makes me think that he meant high middle ages, because we haven't done the chapter on the early middle ages)
Thanks
