Pinki Chauhan, a straight-A Indian physics and math student, arrived at her university campus shortly after breakfast, poured gasoline over her wispy frame and lit a match.

She ran screaming across the college grounds in Gurgaon, near New Delhi, before falling to her knees in flames outside the principal's office. The 19-year-old died a few days later.

Her brother, Arun, said the incident a couple of months ago came after Pinki received zero marks in an exam and argued with her teachers for her paper to be re-marked.
