The female student from Dehiattakandiya who died by using poison, did so not because of an unjust Z score result, but because of a love affair, police spokesman says. The student first received a Z score result of 0.9637 and her district level score was 570. But in the July 22nd Z score result, she had received 1.1121 Z score, and her district level score was 375. So she would have been happy and had no cause to be disappointed with the second result, because it's better than firts results according to a police release.
