The CBSE Class 10 Science exam 2026 is scheduled for 25 February 2026. With only a few days left, students must focus on understanding the CBSE Class 10 Science question paper 2026 pattern & revising the CBSE syllabus for Class 10 Science 2026, and practicing authentic sample papers.
Over the years, CBSE has shifted its focus from direct memory-based questions to competency-based and application-based questions. This means students must understand concepts deeply rather than just memorising definitions. Case study based questions and assertion reason questions are increasingly common. Students who practice official sample papers and previous year CBSE Class 10 Science question papers consistently perform better because they understand how questions are framed.
Science carries 80 marks in theory and 20 marks in internal assessment. The paper duration is 3 hours and includes MCQs, short answer questions, long answer questions, and case study based questions.

CBSE Class 10 Science Question Paper Pattern 2026
Understanding the structure of the CBSE Class 10 Science question paper 2026 helps reduce anxiety and improve time management.
Section A
Multiple choice questions based on Physics, Chemistry and Biology concepts.
Section B
Very short answer questions testing conceptual clarity.
Section C
Short answer questions including numericals and explanations.
Section D
Long answer questions with diagrams and derivations.
Section E
Case study based questions requiring application of concepts.
Students should allocate time proportionally and attempt numericals carefully with proper steps.
CBSE Class 10 Science Marks Distribution and Weightage Analysis
Understanding marks distribution will make you prioritise chapters smartly instead of revising randomly.
Physics generally carries around 25 to 27 marks. Important chapters include Electricity, Magnetic Effects of Electric Current, Light Reflection and Refraction, and the Human Eye. Numericals from Electricity and Ray Diagrams from Light are frequently asked.
Chemistry contributes approximately 23 to 25 marks. Chapters such as Chemical Reactions and Equations, Acids Bases and Salts, Metals and Non Metals, and Carbon and Its Compounds are highly important. Balancing equations and writing chemical properties correctly are essential scoring areas.
Biology carries around 25 to 27 marks. Life Processes, Control and Coordination, How do Organisms Reproduce, and Heredity and Evolution are important chapters. Diagram based questions and definition based short answers are common.
Students should allocate revision time according to weightage instead of giving equal time to all chapters.
