New Delhi, June 11: The Central Board of Secondary Education (CBSE) has received more than 56,000 applications for answer-sheet verification and re-evaluation, even as it successfully thwarted a major cyber attack targeting its online systems during the ongoing review process.
In a statement shared on social media, the board said over 56,000 applications had been accepted by 9.30 pm, reflecting strong student participation in the post-result review mechanism.
CBSE also disclosed that its online platform came under a large-scale denial-of-service (DoS) attack involving approximately 3.8 million malicious data packets. However, the board said its technical teams successfully defended the system and ensured uninterrupted services for students.
“Our technical teams are proactively monitoring performance and introducing refinements to deliver a smoother, faster, and more seamless experience for students,” the board said.
The online facility for verification of marks and re-evaluation of answer scripts became operational on June 2 and will remain available until midnight on June 6. Students seeking review of their examination results have been directed to submit applications exclusively through the online portal.
Under the existing framework, students are required to pay a fee of Rs 100 per subject for verification of marks and Rs 25 per question for re-evaluation.
To strengthen security and improve the authenticity of applications, CBSE has introduced Aadhaar-based authentication for the process this year.

The development comes at a time when the board is facing scrutiny over concerns linked to the recently introduced On-Screen Marking (OSM) system used for evaluating answer scripts.
The issue gained prominence after complaints surfaced regarding alleged answer-sheet mix-ups, discrepancies in marking and errors in grade allocation. The concerns triggered discussions among students, parents and education stakeholders across the country.
Earlier this week, CBSE Chairman Rahul Singh and Secretary Himanshu Gupta were transferred following controversy surrounding the digital evaluation process.
In response, the government constituted a one-member inquiry committee headed by S. Radha Chauhan to examine the procurement and implementation of the On-Screen Marking system.
The panel has been tasked with reviewing the process and submitting its findings to the Department of Personnel and Training within one month.
The OSM controversy also attracted attention after Class 12 student Sarthak Sidhant presented observations on the digital evaluation system before a parliamentary committee on education. His presentation reportedly highlighted concerns relating to the marking process and received appreciation from committee members.
Despite the ongoing controversy, CBSE officials have maintained that efforts are being made to ensure transparency, efficiency and reliability in the examination and review process.

Education experts note that the high number of re-evaluation requests reflects growing awareness among students regarding available review mechanisms and the increasing reliance on digital systems in large-scale examinations.
With lakhs of students depending on CBSE examination results for higher education admissions and career opportunities, the board’s ability to maintain secure and efficient online services remains crucial during the re-evaluation period.
