CBSE Syllabus for Classes 10 and 12 for the coming year has been released, and term wise exams have been discontinued.
The CBSE Curriculum 2022-23 for Classes 9 to 12 has been released. The board has released the revised syllabus for the single board exam pattern, which was previously the norm. Term exams have been eliminated in favour of a single exam. On the official website cbseacademic.nic.in, you can find the CBSE Board Exam 2023 syllabus.
The CBSE Board Exam 2022 curriculum has been released for students in classes 10 and 12. For major subjects, the revised syllabus has seen even more cuts this year, with the board deciding to keep the number of chapters limited for this year as well. Apart from that, the CBSE syllabus is not divided into terms, implying that term-based board exams will be phased out in March and a single board exam will be reinstated.
On the official website cbseacademic.nic.in, the CBSE Class 10, 12 Revised Syllabus for Board Examinations 2022-23 is now available. While a detailed report on the actual cuts is still pending, the teachers have revealed that some chapters and units have been removed and others have been added back. The board, on the other hand, maintains the 30% cut overall.
Students can check the revised syllabus and curriculum for Class 10 Math and Science are given below:
