Hi Santosh,

      I am here to help you with your question. First of all, I want to inform you that we can't really estimate the number of students who got 600+ because the competition is increasing day by day. So let me tell you that in 2018 around 1500 students got 600+ and In 2017 around 2700 students got 600+. I think you can see that there is a lot of difference between 2017 and 2018 that's why I said it is difficult to estimate.

All the best.

Thank you.
