Dear aspirant,
As you have mentioned that you want to know about the marks vs rank prediction so let me tell in these type of private exams the dynamics change a lot because the number of students appearing for the examination is different and so the prediction will vary.
But as per my knowledge you need to score atleast 150+ to be on a safer side.
