Hello Siva

Hope you are doing fine and great

With reference to your query, I would glad to tell you that admission criteria of sastra university is not based completely on  jee mains percentile.It is based on 12th percentage and jee main mark(sastra will calculate like this 12th percentage * 0.75+jee main mark * 0.25) . Overall marks are out of 165 ,based on which they will give you the seat . Due to variation in number of application every year,cut off also varies

Hope you found this answer helpful. Good luck for your future
