Bengaluru: Students of Class 10 and those from the commerce and humanities streams of Class 12 got high scores in the CBSE results, but maths and physics proved dampeners.Teachers recalled how many students walked out of the exam hall in tears. Delhi Public School-Southprincipal Anitha Bijesh said: “Maths and physics brought down the scores of science students. The average score in maths was 77%, and (that in) physics was 82.5%. It was expected as the papers were really tough, and the teachers saw the trend during valuation. However, the scores in other streams remained good.”Mount Carmel Central School principal Sister Melissa noted a discernible shift in the difficulty level of the Class 12 physics exam paper over the past two years.She recalled a time when students frequently achieved 100 out of 100. Now, only one student secured a high of 97 in physics.Some schools said even though the papers were tough, many students performed satisfactorily in physics, considering there were no indications of grace marks. “The physics exam was tough; however, the students did well,” said a college principal from Mangaluru.Nandini Bhat, principal of GEAR Innovative International, said: “Considering the paper was tough, the physics marks were satisfactory. Many questions were (of) college level, JEE standard, and some even out of syllabus. However, the scores in maths could have been better. Even though there were tricky questions, we thought the well-performing students would have done better.””At the same time, English went exceptionally well. Some other subjects in humanities and commerce were equally good,” she added. Seema Goel, of AECS Magnolia Maaruti Public School, said: “Even though the papers were hard, the sample papers gave an idea of what the exam would be about. The students were aware that competency-based questions would come, and the schools had prepared them for it. That’s what helped students score well despite the hard papers.””The scoring in Class 10 was extremely good this time. At least 134 of the 226 students secured more than 90% marks. The number of students who got more than 95% also increased this time,” said Jayanthi Nair, principal ofNational Public School-Banashankari.
