CBSE used its new OSM system for the digital evaluation of Class 12 answer sheets this year.The issue escalated when a Delhi student, Vedant Shrivastava, requested scanned copies of his answer sheets on May 19 after receiving what he described as “unexpectedly low marks” in Physics.After receiving the scanned copies on May 23, he realised that the Physics answer sheet linked to his roll number did not belong to him.He pointed out the issue in a post on X and uploaded side-by-side screenshots from his English and Computer Science papers to show that the handwriting in the Physics script was different. CBSE admitted the error and provided him with his correct answer sheet, but not before the student was trolled online and even called a “Pakistani” for merely raising the issue.
