Patna, June 8 (IANS): Train and road services were hit in Bihar on Thursday as student organisations affiliated to the Left parties went on strike to protest the large-scale failure of Class 12 students in the state board exams.

"Hundreds of students with flags and banners in their hands forcibly stopped trains in Ara, Patna, Vaishali, Begusarai, Jehanabad and Gaya districts," a police officer said.

Road traffic was also disrupted at several places as the agitating students blocked national and state highways, the officer said.

The strike, supported by the Communist Party of India, comes 10 days after over eight lakh students failed in the Class 12 exams conducted by the Bihar School Examination Board (BSEB). 

Chief Minister Nitish Kumar has assured that the failed students could apply online for re-evaluation or verification of their answer sheets.

These results would be out within a month. He has also promised that the BSEB will hold compartmental exams soon.

In a repeat of the 2016 events, the BSEB on June 2 cancelled the results of Ganesh Kumar, the Class 12 topper in Arts and arrested him for committing forgery among other charges.
