Top Preparation Tips for BSEB Class 12 Physics Exams (2026)
The Bihar School Examination Board (BSEB) includes physics as a key topic for students enrolled in the 12th grade in the Science stream. A student's aptitude for Physics can be developed as a platform for future careers in Engineering and Medical Sciences, as well as in Aviation, Technology and Research. There are several reasons why students may struggle with Physics, including the mathematical nature and the underlying concepts that are necessary for success; however, with a proper Study Plan, BSEB Physics may become one of the easiest subjects on which a student can score well in their Intermediate Exam.
This study guide is designed for students working towards a grade of 60+ out of 70 on their Theory Paper and for those who want to earn Full Marks in the Practical component.
1.0Strategy Setup: Understand the BSEB Physics Paper Format
A well-conceived journey towards exam preparation starts with a good grasp of the exam pattern, marking scheme, and chapter-wise weightage established by the Bihar Board. Having this knowledge of the blueprint will enable you to plan correctly, determine which topics should be given precedence, and create a sensible study plan that reflects the requirements of the particular examination.
Official BSEB Marks Distribution
- 70 Marks – Theory (Written Exam)
- 30 Marks – Practicals / Internal Assessment
- 100 Marks – Total
Prioritize High-Weightage Units
Bihar Board follows the NCERT-based Physics curriculum, and certain chapters consistently appear with high marks. Focusing on these units first helps maximize scoring potential.
Score Section A First (OMR Section)
Section A contains 35 MCQs, each worth 1 mark, and is one of the easiest scoring sections in the BSEB Physics paper.
Focus on:
Definitions
SI Units
Graph-based questions
Basic formulas
Concept snapshots
NCERT theory lines
2.0Core Study Techniques for BSEB Physics
Physics requires an understanding of concepts, strong visualization skills, continued practice of numerical calculations, and mastery of derivations. These learning methods will allow you to gain a good grasp of physics and therefore the ability to work with it at an advanced level and not simply through rote learning.
Strengthen Conceptual Understanding
Physics is application-based, so clarity of concepts is essential. Focus on:
- Meaning of physical quantities
- How laws apply to real-life situations
- Cause–effect relationships
- Graphical interpretation of motion, fields, waves
- Core logic behind formulas
Use a concept notebook to summarize definitions, principles, diagrams, and graphs.
Master Numericals & Formula Applications
Most 3-mark and 5-mark questions in BSEB are numerical in nature.
Make a habit of solving:
- 3–5 numericals daily
- 1 long numerical every alternate day
Important numerical-focused chapters:
- Current Electricity
- Electrostatics
- Electromagnetic Induction
- AC Circuits
- Ray Optics
- Semiconductors
Maintain a formula handbook with derivations, variable meanings, and SI units.
Perfect Derivations, Graphs & Diagrams
Derivations fetch high marks when written in proper steps, with assumptions clearly mentioned.
Important Derivations to Practice
- Gauss’s Law applications
- Lens Maker’s Formula
- Drift Velocity equation
- Wheatstone Bridge balance condition
- Transformer and AC formulas
- YDSE fringe width
Important Diagrams
- Ray diagrams for lenses & mirrors
- LCR circuit diagram
- Electric field lines
- Magnetic field around a solenoid
- Photoelectric effect graph
3.0Effective Revision & Practice Blueprint
In order to retain concepts, practice numericals, and improve how you present your answers, taking time to revise is an essential part of this process. Creating a systematic/structured revision plan helps with memory retention, increases your ability to solve problems more quickly, and gives you more confidence when dealing with more challenging types of problems in Physics.
Solve Previous Year Papers (PYQs) with a Timer
Start solving PYQs when 70% of the syllabus is completed.
Practice Plan
- 1 PYQ every weekend (initial phase)
- 2–3 PYQs per week (pre-exam phase)
- Review mistakes after every attempt
Simulated exam practice builds confidence and improves writing consistency.
Time Management for BSEB’s 3-Hour Paper
Answer Presentation & Stepwise Writing
A clean, structured answer impresses the examiner and helps you earn full marks.
Follow This Pattern:
Write formula → substitute → calculate → final answer
Draw clean & labelled diagrams
Box the final answer
Use bullets, not paragraphs
Highlight units & assumptions
4.0Subject-Specific Focus Areas (Physics Units)
The following chapter-wise revision plan for each unit covers strategies appropriate to the level of difficulty and exam weightage of each unit in Physics in relation to the BSEB exams:
