CBSE Class 10 Science Exam on 25 Feb, What’s New This Time?
CBSE has revised the Class 10 Science Exam Pattern 2026 by dividing the 80-mark theory paper into three subject-specific sections—Biology (30), Chemistry (25), and Physics (25). The paper includes 39 compulsory questions with MCQs, short, long, and case-based formats. Answers must be written section-wise.
CBSE Class 10 Science Board Exam 2026, scheduled for 25 February 2026, comes with a more structured and subject-focused format. The board has redesigned the question paper to ensure balanced evaluation across Biology, Chemistry, and Physics while promoting competency-based assessment.
The total theory marks remain 80, but the paper is now clearly divided into three subject-specific sections. Students must carefully follow section-wise answering instructions, as mixing responses across sections may lead to non-evaluation.
