iSheikh, don't gamble. Though your optimistic idea of the expected paper is good, it might not necessarily be that way. Even if it is, you have to know history really to talk like a historian. And history subject examiners are so irked with vague conceptions and unreflective narrations that they tend to vent their tempers on reductionist answers.

Better not opt Islamic History if you cannot devote at least 25 14-houred days to the subject.

Best!
