What should be done with crossed out work on a candidate's response?

The approach to dealing with crossed-out work is important for ensuring fairness and clarity in the assessment process. When a candidate crosses out a response but provides a new answer, option B correctly states that the crossed-out responses should be marked through unless they are replaced by new answers. This means that the crossed-out work is effectively disregarded, but the intention behind marking through is to delineate clearly what is not part of the final submission.

By marking through those responses, the examiner can focus on the answers that the candidate has chosen to retain, which allows for precise assessment of the candidate's knowledge and skills. This approach respects the candidate's thought process, as it acknowledges that initial answers may not reflect the final decision, and it prevents confusion during the marking process. It's a systematic way to manage the paperwork and ensure that the final answers are evident and clearly communicated.
