CBSE Class 10 Science & Social Science Question Paper Splitted? Know New Changes in Re-evaluation Process

Splitting of CBSE 10th Science & Social Science Paper in 2025-26

The CBSE 10th Board Science paper covers various disciplines like chemistry, biology, and physics, whereas the CBSE 10th Social Science covers political science, geography, history, economics, etc.

• The Science and Social Subject disciplines are taught by various subject matter experts at school for the CBSE 10th Board exam but students attempt the subjects in one as a composite paper.
• During the CBSE 10th evaluation process, the board may ask the evaluator who is an expert in biology (for example) to evaluate the entire paper which also includes other disciplines like chemistry and physics.

Will the CBSE Revise the Board Syllabus?

The Board is expected to revise the CBSE Class 12 applied mathematics syllabus. The textbook content and the syllabus are being reviewed by the board to suggest new changes in the curriculum. The board is planning to propose the use of calculators in the CBSE 12th accountancy examination from the academic year 2025-26. The CSBE 12th Applied Mathematics exam revisions will be conducted in two phases.

• Phase 1: Class 11 textbook syllabus revision in 2025.
• Phase 2: Class 12 syllabus revision in 2026.

CBSE Board On-Screen Marking System (OSM)

The Central Board of Secondary Education proposed a new scheme of “On-screen Marking” of question papers which helps examiners to cut short their time spent during the evaluation process of CBSE 10th answer books. The board proposes to implement the OSM system in the 2026 examination in a few subjects to avoid administrative difficulties. The CBSE on-screen marking system will be tested in the following -

• CBSE 10th Science examination
• CBSE Class 10 Social Science examination
• CBSE 10th Class Mathematics
• Supplementary examination
• Revaluation

Was the CBSE On-Screen Marking System Implemented Before?

The CBSE board had earlier implemented the OSM system for certain subjects in the 2013-14 examination. The board had taken help from private agencies like TCS to get digitised answer books to the evaluation centres and evaluators. The CSBE further stated that the on-screen evaluation system was satisfactory in regions like Panchkula, whereas, the OSM was difficult in regions like Patna, Prayagraj, and Ajmer.
