Focus and fun, and not long hours of studying, are the secrets behind the high marks scored by some of the CBSE Class 12 toppers this year. “I don’t think studying for five or 10 hours a day will give you good marks. It will only give you cervical pain,” said Sarthak Agarwal, who secured 99.6 per cent marks, in an interview to Headlines Today.He also said that he never bothered what others were saying. “I was always focused”.”I participated in all extra-curricular activities and I had fun too. But yes, I studies too”, said Aastha, who secured 98 per cent marks.”I am a fun-loving person. I am active in sports and co-curricular activities. I used to hang out with friends, listen to music and still all of us in the group scored above 90 per cent,” said Harshita, who got 93.2 per cent marks.
