What should candidates ensure about their answers on the examination?

Candidates should ensure that only one answer is marked for each question because most examinations, including the Massachusetts State Police Sergeant Practice Exam, typically use a standardized answer sheet where selecting multiple responses can lead to confusion and incorrect scoring. Marking only one answer demonstrates a clear choice and allows the evaluators to properly assess the candidate's knowledge and decision-making skills. This single-answer requirement helps maintain the integrity of the exam process and ensures that answers are scored accurately.

While other aspects of answering questions, such as clarity and checking responses, are important, they do not carry the same critical impact as properly marking answers. Clear markings can assist in scoring, and double-checking can definitely help avoid mistakes, but the fundamental expectation is to select one answer to indicate the test-taker's conclusion for each question.
