Karnataka 2nd PUC Physics Question Paper Design
Time: 3 Hours 15 Minutes (of which 15 minutes for reading the question paper).
Maximum Marks: 70
The weightage of the distribution of marks over different dimensions of the question paper is as follows:
A. Weightage to Objectives:
B. Weightage to Content/Subject Units:
C. Weightage to forms of Questions:
- Questions in IV Main must be set from Unit I to V.
- Questions in V Main must be set from Unit VI to X.
- Questions in VI Main must be set such that one Numerical Problem is from every 2 successive units.
D. Weightage to the Level of Difficulty:
- Questions should be clear, unambiguous, understandable and free from grammatical errors.
- Questions which are based on the same concept, law, fact etc. and which generate the same answer should not be repeated under different forms (VSA, SA, LA and NP).
- Questions must be set based on the blowup syllabus only.

2nd PUC Physics Practical Exam Marking Scheme
- Duration of practical examination: 2 hours.
- Maximum marks allotted: 30 marks.
- At least TEN (10) different experiments have to be set in the practical Examination.
Scheme of Evaluation
A. Weightage of Marks
|I||Performing the Experiment||20|
|II||Viva – Voce||4|
B. Distribution of Marks
I. Performing the Experiment
- Writing the principle of the experiment (2 Marks)
- Writing the formula and explaining the terms (2 Marks)
- Writing the diagram/figure/circuit with labelling (At least two parts) (2 Marks)
- Writing the tabular column/observation pattern (2 Marks)
