ISC Class 12 Physics Weightage 2025

Theory Exam (70 marks): The theory exam is divided into two sections:

• Section A: Includes 10-12 short-answer questions that are compulsory.
• Section B: Contains 6-8 long-answer questions with internal choices.

Internal Assessment (30 marks): This portion includes practical work, assignments, projects, and other assessments, which are conducted and evaluated by the school, with an external examiner involved for the final evaluation.

Note:

• Optics carries the highest weightage (18 marks), making it a critical area of focus.
• Magnetic Effects of Current and Magnetism contributes significantly, with 16 marks.
• Chapters like Dual Nature of Radiation and Matter and Electronic Devices are relatively lighter but still essential with 7 marks each.

Practical and Project Work Evaluation Criteria

1. Practical Exam (15 Marks)

• Ray Optics : Includes topics like refraction, reflection, and lens experiments.
• Current Electricity : Includes experiments related to circuits, resistances, and measuring instruments.

2. Project Work (10 Marks)

Theoretical Project : This involves a detailed study and analysis of a specific topic. The project should include:

• Title and Introduction
• Detailed Content and Analysis (graphs, data, pie charts, diagrams, etc.)
• Originality of work
• Conclusion/Comments

Working Model : Students can create a working model related to any topic in Physics. The evaluation includes:

• Title of the project
• Construction of the model
• A concise project report explaining the concept.

Investigatory Project : This involves designing and conducting an experiment. The project report must include:

• Title and Theory/Principle Involved
• Experimental Setup
• Observations, Calculations, and Graphs
• Result/Conclusion

3. Practical File (5 Marks)

• Completeness and organization of records.
• Neatness and clarity of presentation.

Study Tips for ISC Class 12 Physics 2025

Focus on High-Weightage Units :

• Dedicate more time to Optics , Electrostatics , and Magnetic Effects of Current and Magnetism , as they carry the maximum weightage.
• Strengthen your concepts in these chapters with numerical practice and derivations.

Revise Practicals Thoroughly :

• Perform all experiments during lab sessions and maintain a well-documented practical file.
• Review the theory behind each experiment for better understanding.

Prepare for the Project :

• Choose a topic that interests you and aligns with your strengths.
• Ensure originality in your work and include graphs or visual aids for better presentation.

Time Management :

• Allocate time wisely, focusing more on chapters with higher marks allocation but not neglecting smaller ones like Atoms and Nuclei and Electronic Devices .

Solve Previous Years’ Question Papers :

• Practice previous years’ ISC Physics papers to familiarize yourself with the question pattern and marking scheme.
