A 20-year-old Indian student from Cornell University hacked into the database of ICSE (Class X) and ISC (Class XII) school exam results, exposed glaring anomalies in the marking system and went on to merrily write about his exploits in an online post.

Kolkata-born Debarghya Das, majoring in computer science, says that all he had to do was run a simple program that entered all roll numbers after defining a range to get access to all the results. “It is shocking they haven’t implemented a more secure system,” Das told TOI on phone from New York.

After the result’s data was crunched, analysed and plotted in graphs, Das discovered an interesting incongruity in the marking system: there are 33 different scores unattained between the passing mark of 35 and the maximum of 100 by the nearly 1,50,000 who appeared for the ICSE (Class X) exam. According to Das’ findings, not a single student got the following marks: 36, 37, 39, 41, 43, 45, 47, 49, 51, 53, 55, 56, 57, 59, 61, 63, 65, 67, 68, 70, 71, 73, 75, 77, 79, 81, 82, 84, 85, 87, 89, 91, 93. Similarly, in the case of ISC (Class XII exam) a set of 24 marks between 40 and 100 were found to be unattained.
