CBSE Grade 10 Overview

• CBSE is the Central Board of Secondary Education.
• Grade 10 is a crucial year with board examinations.
• Grade 10 results are influential when choosing streams for Grades 11 and 12, like Science, Commerce, or Arts/Humanities.

Subjects Typically Included

• Language 1 (usually English) focuses on language proficiency, comprehension, and writing skills.
• Language 2 (usually Hindi or a regional language) aims to develop a second language.
• Mathematics covers arithmetic to algebra, geometry, trigonometry, and statistics.
• Science includes Physics, Chemistry, and Biology, providing a foundation in scientific principles.
• Social Science integrates History, Civics (Political Science), Geography, and Economics for a broader understanding of society.

Examination Structure

• The CBSE conducts board examinations for Grade 10.
• Examinations are usually held in March.
• Assessment includes theory and practical/internal assessments.
• The relative weightage of theory and internal assessment marks can vary across subjects.

Assessment and Evaluation

• CBSE follows a grading system.
• Absolute marks are converted to grades.
• The grading system uses letter grades (A1, A2, B1, B2, C1, C2, D, E).
• There is no overall pass or fail; each subject is graded independently.
• Students must obtain a qualifying grade in each subject to be declared successful.
• Internal assessments are conducted by the school and contribute to the final grade.
