Patna: Stung by the media expose of 'dubious' toppers of Std XII examination conducted by Bihar board, state education minister Ashok Choudhary yesterday said a high-level probe has been ordered to re-check merit of the toppers.

Both toppers hail from Bishun Rai College in Bhagwanpur in Vaishali district. The probe would be conducted in all the three streams — Humanities, Science and Commerce —and merit of examiners who awarded the marks would also be checked, Choudhary said.

Video of a girl who topped the state government’s Std XII examination in Humanities pronouncing Political Science as ‘Prodigal Science’ and describing it as a subject related to cooking, while that of a boy who topped in Science but was unaware of electron and proton, exposed the results of the exam conducted by Bihar School Examination Board (BSEB) this year.
