New Delhi, Mar 30: The protests against the Central Board of Secondary Education’s (CBSE) decision to conduct re-examination for Class 10 Maths and Class 12 Economics papers have spread across India. After Delhi, hundreds of students on Friday protested against the CBSE paper leaks and re-examination in Punjab and Uttar Pradesh among other states. Students demanded that re-examination be cancelled.

Section 144 has also been imposed at Human Resource Development Minister Prakash Javadekar’s residence on Kushak Road amid protests by students. Tight security has been deployed around the minister’s residence. The PTA members of Mumbai have written to Javadekar seeking time to meet. They have also requested him not to conduct the re-examination of Class 10 Maths paper, saying there was no paper leak in the Mumbai region.

On Thursday, protesting students alleged that the leaked question papers of Maths and Economics were being sold outside a Delhi school for Rs 8,000 to Rs 16,000. They also claimed that the question papers of other subjects were also leaked and were being distributed in exchange for money.

Meanwhile, the Delhi Police Crime Branch continued questioning people on the paper leak cases. Since Thursday, the Delhi Police have questioned over 30 people in connection with the Class 10 Maths and class 12 Economics paper leak cases.

The CBSE had on Wednesday announced that it would be re-conducting the examination of class 10 Maths and class 12 Economics papers in wake of the paper leak. The dates of the re-examination are likely to be announced on April 2.
