Dear aspirant,

I would like to request you that kindly provide the name of the entrance examination which you have given so that i could be able to guide you well in this matter.

But without the basic details i won't be able to guide you in a descriptive manner. However 79 percentile is a good score as per your category is concerned .

Regarding the cut offs there are various factors that decides cut offs like number of candidates appearing in the examination, number of vacant seats in college, previous years cut offs and difficulty level of the paper.
