The central board added that the portal also saw more than 1 lakh attempts of unauthorised file access.

“Based on student feedback, we have further refined the platform, including extending session time limits to make the process more convenient and seamless. Our teams remain vigilant and responsive to ensure our dearest students are facilitated in all ways possible,” the board added further.

The board's portal opened after multiple delays and was initially set to go live for students on May 29.

However, CBSE deferred the launch to June 1 to ensure a "transparent and error-free process."

The board's re-evaluation portal was opened amid the ongoing row regarding its on-screen marking process.

Amid the row regarding the board's OSM portal, the Ministry of Education has sought a detailed report from CBSE and the contract awarded to Hyderabad-based Coempt EduTeck.

Earlier today, a parliamentary panel also heard the issues regarding the on-screen marking portal as well as the implementation of the three-language policy for Classes 9 and 10.
