At least 20 Indian students have killed themselves after wrongly receiving failing grades on highschool final exams. Nearly 1 million students in the southern state of Telangana took the tests between February and March, and some 325,000 were failed, causing widespread protests by parents and students. Officials had outsourced the grading to a private firm, which apparently used faulty software. Some students who took the test were marked absent, while others were given a zero for subjects they completed. One 17-year-old girl set herself on fire after getting her results. Telangana Chief Minister K. Chandrasekhar Rao ordered free regrading of answer sheets for all the failed students, and he appealed to them not to commit suicide.
