Bihar Board Class 11 Biology Syllabus
Students must stick to the BSEB syllabus guidelines to avoid confusion. It includes all the chapters from which questions will appear in the exam.
The first chapter holds important significance as it includes the basic terms of Chemistry. Students should begin with the first chapter ‘Some Basic Concepts of Chemistry’ to understand the basic terms like atomic mass, chemical formula, and mole.
The practical exam also holds importance to achieve an overall good score. A good performance in Class 11 practicals not only helps in scoring well but also helps students to understand logic behind every equation.
It is important to know the short tricks and the important formulas by heart. Students must write all the tricks and important formulas, especially for Physical Chemistry (Mole concept, gas laws, and thermodynamics) in a notebook and revise them regularly to reinforce learning.
Solve Previous Years’ Papers to understand the exam pattern and practice questions from it to test your knowledge.
