Hey Aman.

The cut off for qualifying the second stage of NTSE from Madhya Pradesh was around 135 marks out of 150 in the previous year. The cut off varies each year due to various factors like level of competition, difficulty, number of candidates and more. Hence you can expect the cut off in a Similar range out of 200. This year the maximum marks were also 200 instead of 150. Rest would depend on the factors.

Best of luck
