Based on the data received from the students till now, it appears that the cut-off was around 70 marks aggregate which is around 10 marks more than what I had expected. It still is an approximation. The picture will be very clear as far as total cut-off, subject-wise cut-off and screening cut-off are concerned as more students send their marks in due course.
Maths seems to have decided the ranks in case of tie whose cut-off appears to be less than 10 which is as expected.
