Answer evaluation for numerical problem-solving questions in the Electrical Engineering optional subject is typically done based on the correctness of the solution provided by the candidate. Here is a detailed explanation of how the answers are evaluated:


- The first step in evaluating the answer is to check the approach and methodology used by the candidate.
- The candidate's understanding of the problem, ability to identify the relevant concepts, and selection of appropriate equations or formulas are considered.
- The examiner looks for a well-structured and logical approach to solving the problem.


- The next step is to evaluate the correctness of calculations performed by the candidate.
- The examiner checks the accuracy of numerical computations, including intermediate steps and final results.
- The candidate's ability to perform calculations accurately is crucial in determining the correctness of the answer.


- The evaluation also includes checking the units and significant figures used in the answer.
- Electrical Engineering problems often involve quantities with specific units, so it is important for the candidate to provide answers with the correct units.
- Additionally, the candidate's understanding and application of significant figures are assessed to ensure the precision of the answer.


- The presentation of the solution is also taken into consideration during evaluation.
- The candidate's ability to present the solution clearly and concisely, using proper mathematical notation, is evaluated.
- Neatness, organization, and clarity of the answer are important factors that contribute to the overall evaluation.


- In some cases, partial credits may be awarded for correct intermediate steps or partial solutions.
- This is done to acknowledge the candidate's understanding of the problem and their progress towards the final answer, even if they made a mistake in the final calculation.


- Lastly, the examiner may analyze any errors made by the candidate.
- This helps identify common misconceptions or gaps in the candidate's understanding, which can be used to provide feedback for improvement.

Overall, the evaluation of answers for numerical problem-solving questions in the Electrical Engineering optional subject is based on the candidate's approach, correctness of calculations, units and significant figures, presentation, and error analysis. This ensures a fair assessment of the candidate's understanding and problem-solving skills in the subject.
