Sarthak Sidhant, who raised concerns about alleged irregularities in the Central Board of Secondary Education's (CBSE) On-Screen Marking (OSM) system, on Sunday sought an extension of the re-evaluation deadline, which ends today, saying that he had been "busy exposing" the board this week. “Can u please extend the deadline please because i was busy this week exposing you,” Sidhant said on X. The CBSE on Friday announced a one-day extension of the deadline for Class 12 students to apply for verification of marks and re-evaluation of answer scripts. Students can now submit their applications until June 7. The decision was taken after several students reported difficulties in accessing their answer sheets and completing the verification and re-evaluation process through the CBSE's post-result services portal, which became operational on June 2.

"In the interest of students, the CBSE has decided to extend the last date for submission of applications for verification and re-evaluation for the Class 12 board examinations, thereby providing students additional time and support to complete the process," the board wrote on X. "Students are requested to take note of the revised schedule and submit their applications accordingly," it added. The CBSE said the deadline, originally set for midnight on June 6, has been extended by 24 hours and will now remain open until midnight on June 7.
