According to the Measures for Handling Violations in National Education Examinations, procrastination is illegal. If the examinee violates the rules, there should be a notice of violation for you to sign. Only when the formalities are complete can the examination institute determine that you have violated the rules.

You didn't receive it, which means that the test center didn't think it was a thing at all, and there is no need to determine that you violated the rules.
