1, time limit for answering questions. The time for answering each question can be limited. If there is no answer after the timeout, the system will automatically jump to the next question to minimize the possible cheating time of candidates.

2. Random order. Support the random order of questions and the random choice of multiple-choice questions, and it is difficult for candidates to pass the answers to each other.

3. Prevent screen cutting. Candidates are not allowed to cut or split the screen during the exam, otherwise the system will automatically hand in the papers to end the exam. At the same time, candidates who trigger the anti-screenshot rule and hand in their papers automatically will be marked as "suspected of cheating" in the exam results to attract the administrator's eye-catching prompt.

4. Face recognition. Face recognition will be conducted before the exam to confirm the identity of the candidates, and there is absolutely no substitute for the exam.

5. Camera monitoring. During the examination, the system will use the camera to take pictures of candidates at random moments to avoid face recognition before the examination and prevent candidates from cheating in reading and viewing offline materials during the examination.

6. Handwritten signature. Everyone's writing habits are different. Handwritten signature can be used as an auxiliary proof to confirm the true identity of candidates without deliberate imitation.

7. Prohibit the terminal. Administrators can ban some test terminals, such as mobile phones, computers, web pages, etc. , thus forcing candidates to use the terminal allowed by the exam.

8. Screen test. An independent program will be used to take the exam. During the examination, candidates can't leave the examination screen, and the examination environment is always at the top, covering any old and new windows. The examination environment can only be closed when candidates hand in their papers and leave the examination room.
