Students on Thursday protested the CBSE paper leak at Jantar Mantar, raising slogans of "we want justice". The CBSE received a complaint naming a person from Delhi's Rajinder Nagar as being behind the leak of Class 10 and 12 examination papers.
More than 2.8 million students have been affected by CBSE's decision to re-conduct examination for two papers of Class 10 and 12. According to the CBSE, a total of 1,638,428 and 1,186,306 students had registered for examination this year for Class 10 and Class 12, respectively. Therefore, over 2.8 million candidates of both classes would have to re-sit the exams due to the board's inability to keep its test papers secure. The fresh dates for the two re-examinations shall be announced before the end of the week.
