What is the guideline regarding contradictory answers in exams?

The guideline regarding contradictory answers in examinations emphasizes the importance of consistency and clarity in responses. When students provide contradictory answers, it can demonstrate a lack of understanding of the material, which can confuse the person grading the exam. Disallowing contradictory answers means that students are encouraged to think critically and ensure their reasoning aligns throughout their responses.

This approach maintains the integrity of the evaluation process, as consistency is crucial in assessing a student’s grasp of the subject matter. It encourages learners to review their answers and promotes a deeper engagement with the material, guiding them to provide coherent and logically sound responses. Thus, maintaining high standards of clarity and consistency is essential for accurately assessing a student's knowledge and skills in building services engineering.
