dear
as the time is short so you better go through past papers.....by reading with respect to papers you can get clue of what the examiner wants....try to fictionalize your writing in paper while discussing mughals and dehli saltanat rulers.....just like you know someone personally.... or just get PDF copy of Muslim rule in India by Dr ishwari parsaad from archives.org .....by reading ishwari parsaad you get my clue

never ever criticize any Muslim ruler for example ,Aurangzeb demolition of temples or fratricidal wars in Muslims

in mentioning India........write it as "indo-pak"

in paper if you are not certain of any date,just leave it but never write false date
