Understanding the 80/20 Rule in Class 10
In the CBSE Class 10 evaluation system, the 80/20 rule refers to the division of marks between theory and internal assessment.
80 marks: Board theory examination
20 marks: Internal assessment (projects, practicals, periodic tests)
Both components are crucial for the final score, so students should ensure their internal records are complete.
