Patna: While many school students in India these days are taking a sigh of relief as their results are being declared at short intervals, it seems that a Pandora's box has been thrown open for the 'toppers' of Bihar Board Class XII examinations.

In one of the latest updates in Bihar Board Class XII Exam 2016 Results, Bihar School Examination Board (BSEB) Science topper Saurabh from Hajipur failed in the re-examination, ANI reported on Saturday.

Furthermore, the results of two students – Saurabh and Rahul - out of 13 students have been cancelled by the Bihar School Examination Board.

The development comes days after the Bihar School Examination Board had ordered a probe into the exam results and on examiners after a video allegedly showed one of the state-level toppers mispronouncing 'Political Science' and calling it a subject about one's cooking skills.

However, the exam board`s head Lalkeshwar Prasad Singh had informed yesterday that Bihar`s Class 12 `topper` in Arts, Rubi Rai, who said political science is all about cooking, will face stern action for failing to appear in a re-test on Friday.

He said Ruby's father had sent an application stating that she was under "depression" and so could not turn up. "She has gone outside for treatment for her mental depression prior to the publication of the board's advertisement which asked her and other 13 rank holders to appear for the test on June 3," the Chairman said.

In the application, Ruby's father sought more time for her appearance. "She will prove her ability once she recovers," he said in the application. Nand Kishore Yadav, Deputy Director of Bishun Rai College, where the student had studied carried the letter to the board.

Both Ruby and Science topper Saurabh Kumar hail from Bishun Rai College in Bhagwanpur in Vaishali district which is in the eye of a storm after the media expose.

Some news channels had earlier shown the girl, who topped the state government's plus two examination in Humanities,purportedly pronouncing 'Political Science' as 'Prodigal Science' and describing it as a subject related to cooking.

Similarly, the boy who topped Science stream was purportedly unaware of electron and proton.

Following the expose, the BSEB put on hold the results of the toppers of Arts and Science streams of class XII examination and called 14 toppers of Arts and Science streams for a test before subject experts today.

Science topper Saurabh Kumar whose knowledge of the subject is under a scanner attended the test today. "Those appearing for test today were subjected to a fresh written test and were interviewed on their subjects," the BSEB Chairman said.

On being asked when will the results of the authentication test come out, the Chairman did not specify any time. "The expert committee will first give its report after that it will go to a committee dealing with use of unfair means in examination before the final results," he said.
