Good Luck!

Past two years trends suggest cutoff of 118 to 126 marks in General category and hence even if you add 25marks more as cutoff which cones around 150+ then its great chance for any candidate scoring above 150 to convert NTSE stage2 Telangana under General category.

175 looks very good and high chances  expected.. Do wait for official results.
