Bihar Board Class 11 (Science – PCB) Half-Yearly Syllabus

The Bihar School Examination Board (BSEB) follows the NCERT-based curriculum for Class 11 Science. Although there is no separate public notification for the half-yearly exam syllabus, most schools use the board’s overall Class 11 Science syllabus and divide it into segments for practical internal assessments like half-yearly exams.

1. Physics

Key topics typically covered in the half-yearly portion include:

• Physical world and measurement

• Units and dimensions

• Kinematics (motion in a straight line and motion in a plane)

• Laws of motion

• Work, energy and power

These provide core mechanics understanding, forming the foundation for higher topics.

2. Chemistry

Important chapters expected in the half-yearly syllabus include:

• Some basic concepts of chemistry (mole concept, chemical calculations)

• Structure of atom (atomic models, electronic configuration)

• Classification of elements and periodicity

• Chemical bonding and molecular structure

These chapters cover the fundamentals of chemical theory essential for advanced study.

3. Biology

Likely half-yearly topics include foundational chapters:

• The living world (introductory concepts of biology and life)

• Biological classification (five or more kingdom systems)

• Plant kingdom and animal kingdom overview

• Cell: the unit of life

• Biomolecules

• Cell cycle and cell division

These collectively establish basics of life science and cell biology.

How to Use This for Half-Yearly Preparation

• Check with your school teacher if they are following this split or have a customized chapter list.

• Use the BSEB Class 11 syllabus PDF as the definitive guide and highlight half-yearly-relevant chapters.

• Focus your revision and practice questions on these topics first to align with the half-yearly exam pattern.
