What is the consequence of marking multiple answers for a single question?

Marking multiple answers for a single question typically leads to the answer being voided. This is because standardized tests are designed to have clear and definitive responses to each question in order to maintain fairness and accuracy in scoring. When a student selects more than one answer, it creates ambiguity regarding which response should be considered correct. Consequently, the test administrators often decide that the response cannot be graded, resulting in the voiding of that particular answer. This policy helps ensure that all participants adhere to the same rules, maintaining the integrity of the testing process.
