CBSE Class 8 Revision Notes

Class 8 Revision Notes

The Central Board of Secondary Education (CBSE), is an Indian national-level education board for public and private schools that are controlled and managed by the Government of India. All CBSE-affiliated schools stick to the NCERT syllabus, specifically from standard 9th to 12th.

According to CBSE, Class 8 is viewed as an important class in the academic years of a student. It is a class where students need to learn and establish a foundation for themselves and prepare for the final two years before the 10th board exams. 

The 8th standard is important for a student since it teaches them all of the basic concepts that they will study in their future. It is also important to do well in this standard since it will boost your confidence when you enter class 9.
