Bihar Board Class 11 Biology Syllabus 2026 Preparation Tips 

• Bihar Board Class 11th Syllabus 2025-26 allows students to understand and connect each chapter to another. Biology is a sequential subject, so topics like cell biology should be mastered before moving to plant and human physiology.

• Chapters can be understood based on the diagrams. Chapters like Morphology of Flowering Plants and Anatomy of Plants are rich in diagrams. This makes learning interactive and visual, which also helps in scoring better in exams.

• It is important to refer to the previous years’ papers to analyze the exam pattern and the type of questions that appear in the exam. 

• The Practical section allows students to apply their knowledge to practice. This section not only helps in understanding the theoretical concepts better but also helps you score better.  

• For Biology, students must focus on key concepts, diagrams, and NCERT-based definitions to understand the concepts and score well.
