According to examination rules, which of the following is prohibited?

Referring to notes or books during an examination is prohibited because it undermines the integrity and purpose of the assessment. The goal of a practice exam is to measure a candidate's understanding and knowledge of the material without outside assistance. Allowing the use of notes or books could provide an unfair advantage, skewing the results and making it difficult to accurately gauge a candidate's readiness and competence in real estate practices.

Guidelines for examinations are established to ensure a level playing field for all candidates. By prohibiting external resources, the exam maintains its focus on the individual's ability to recall and apply information, which is critical in real estate practice. This aligns with standard testing protocols in many professional fields, reinforcing the importance of personal mastery over the content.
