The Central Board of Secondary Education (CBSE) has released a revised date sheet for the upcoming board examinations. For the Class 12 Science stream students, the May 13 Physics exam will now be held on June 8. The date sheet is now available at the official website, cbse.nic.in. The Board has reduced CBSE Class 12 Physics syllabus by 30 per cent to compensate for the loss of studies due to the COVID-19 pandemic. The CBSE Class 12 reduced syllabus for all the subjects are available on the official CBSE website, cbseacademic.nic.in.
The deleted portion of Class 12 is applicable only for the upcoming board examinations. Students must check the CBSE reduced syllabus for Physics paper and prepare for their exams accordingly so that they do not waste time studying extra.
