More than eight lakh class 10 students of Bihar School Examination Board failed as the pass percentage dropped from 75 to 46 in a year. That it is also the state’s worst performance in nearly two decades mostly slipped under the radar. Patna fared worse than the state’s average. Only 10% students could secure first division marks, down from 21% last year. The percentage of second-division students dropped from 40 to 25. The number of students who registered themselves but did not appear doubled to 30,000. All this did not happen suddenly. The state had to crack down after images of people risking their life and limb by clambering up a multi-storey school building and clinging on window ledges to help their wards cheat last year drew worldwide derision. Mass copying aided by relatives and friends was known. Now its scale and blatancy had shocked the outside world.
