Calcutta, May 23 :    Calcutta, May 23:  The results of this year's ICSE and ISC examinations, posted on the Net from Tuesday midnight, reveal an improvement in the overall performance of ICSE students in most Calcutta schools. Many lesser-known schools, too, fared better than last year. The examinations, conducted by the Delhi-based Council for Indian School Certificate Examinations, were held in March. Terence Ireland, principal, St James School, and convener of one of the Council's zones in Calcutta, said marksheets 'will reach most schools by Saturday'. A quick survey of results at many Calcutta schools showed a rise in ICSE marks. 'Students have scored high marks in some subjects, like Bengali and Hindi,' observed Father Boris D. Santos of St Xavier's. Maths and science scores were also up from last year. The results of some of the middle-ranking schools was also 'encouraging'. The number of failures has dropped and '100 per cent success rate' was reported from many lesser-known schools. At Rajasthan Vidya Mandir, in north Calcutta, 63 of the 65 ICSE examinees have scored 60 per cent or more. All 67 students from Agrasain Balika Siksha Sadan, in Howrah, passed, with 53 scoring more than 70 per cent. Kingshuk Chakraborty, a physically-challenged student of Future Foundation, scored 91.23 per cent marks. 'We are proud of Kingshuk for his performance,' said Ranjan Mitra, principal of Future Foundation. Kingshuk had taken the test with the help of a writer. The scores at some reputed ICSE schools were also quite high. There was, however, no official confirmation from the Council's city office about top-ranking students in Calcutta. But Shreepriya Das of St Xavier's, with 566, and Milinda Banerjee and Samvit Kanoria of La Martiniere, each with 565, appear to be among the top rankers in Calcutta. Valentina Dutta of La Martiniere for Girls and Nishu Agarwal of Rajasthan Vidya Mandir are a few of the city's high scorers among girls in ICSE, while Arnab Mukherjee and Chirag Mehta of Don Bosco Park Circus have obtained 562 and 560, respectively. Siddharth Sinha and Pallab Agarwal have stood joint first among the ICSE examinees from St James School, with 93.8 per cent, while Sayak Banerjee and Sansaptak Dasgupta from ISC have scored 96.7 per cent each.
