Tina Dabi, a scheduled caste girl from Delhi, has topped the list of successful candidates in the civil services examinations 2015-16. While she was being congratulated, the UPSC let it be known that she had secured just 52 per cent marks. While the revelation may have prompted some sniggers, it did not really matter, because others secured even less. As the first SC candidate in six-and-a-half decades to top the list, Tina created history.
