The Central Board of Secondary Education (CBSE) examinations started on Tuesday on a disappointing note to many, with several class-12 students complaining that the physics paper was too lengthy to finish in three hours. According to students, the physics paper, though easy, could not be completed as the questions marked 2 and 5 were a bit too lengthy. “The paper was easy but lengthy and I could attempt only 70 percent of the questions,” said a nervous looking Ankit Kumar, a student of Kendriya Vidyalaya Jawaharlal Nehru University (JNU) campus in the capital. Some of the students found the questions twisted. “There were no direct questions and we had to draw graphs in several questions. It took a long time. I only wish the other papers are not too lengthy,” Rajul Pandey, a student of Balwant Rai Mehta Vidya Bhawan in Greater Kailash II. According to teachers, students were not satisfied with their performance on the first day. “My students are really not happy. Most of them could not attempt all the questions,” said Asha Singh, physics teacher at Kendriya Vidyalaya, JNU. Parents accompanying their wards were also seen trying to calm them down after the examination. “I told my son to forget the physics paper and start preparing for the March 7 chemistry paper. I hope he does well from now on,” Manisha Singh, mother of a class-12 student, said. Some residential schools held prayer meetings for students appearing for the board exams. “Before the start of the exams, we held a prayer meeting in the school and students chanted the 'Saraswati Mantra',” said a psychologist-cum-counselor with a residential school in south Delhi. Over 1.8 million students are sitting for the board examinations across the country and abroad. This year, 1,061,566 students of Class 10 will appear for continuous comprehensive evaluation (CCE) under the CBSE. As many as 769,929 students – 454,131 boys and 315,798 girls – are appearing for class 12 board exams.
