The Council for the Indian School Certificate Examinations (CISCE) has officially released the ICSE Class Ten Biology exam pattern for the academic session Two Thousand Twenty Five–Twenty Six. The structured assessment framework outlines the distribution of marks between external theory evaluation and internal practical assessment. Biology will continue to carry a total of one hundred marks, divided into eighty marks for the theory paper and twenty marks for internal assessment. The theory examination will be conducted for a duration of two hours in offline mode. The paper will include short answer compulsory questions and long answer choice-based questions, with strong emphasis on diagrams, application-based reasoning, and conceptual understanding.
ICSE Class Ten Biology Two Thousand Twenty Six: Key Exam Highlights
A snapshot of the official exam structure is provided below for clarity:
This structure ensures a balanced evaluation of theoretical knowledge and practical skills.
Distribution of Marks Between External and Internal Assessment
The percentage-wise division of marks has remained unchanged for Biology:
Internal assessment will be based on laboratory practical work, project submission, and continuous evaluation throughout the academic session.
ICSE Class Ten Biology Two Thousand Twenty Six: Unit-Wise Weightage
CISCE has also released the unit-wise mark distribution for Sections A and B, helping students identify high-scoring areas.
The combined total of Section A equals forty marks, and Section B equals forty marks, confirming that the theory paper carries eighty marks in total
High-Weightage Topics for Focused Preparation
Based on the official weightage, the following units carry the highest scoring potential:
- Nervous System – Sixteen Marks
- Genetics – Thirteen Marks
- Photosynthesis – Thirteen Marks
- Sense Organs – Nine Marks
- Circulatory System and Reproductive System – Eight Marks each
Education experts advise students to give maximum priority to Human Anatomy and Physiology and Genetics, as these units together account for a significant portion of the total paper.
Question Pattern and Evaluation Method
Section A will consist of compulsory short answer questions testing fundamental concepts. Section B will contain long answer descriptive questions with internal choices, requiring students to attempt any four questions. Diagrams, reasoning-based answers, and clarity of biological processes will carry strict marking standards. Internal assessment will evaluate students on:
- Laboratory experiments
- Biology project work
- Practical record submission
- Continuous classroom observation
What Students Should Note for the Two Thousand Twenty Six Board Exam?
- Strong command over conceptual clarity and diagrammatic representation remains essential.
- Human Physiology units together contribute more than forty percent of the theory paper.
Internal assessment continues to hold twenty marks, which can significantly improve overall scores.
