Notes on answering questions in the Civil Service Examination:

1. After getting the answer sheet, you must check whether your answer sheet is intact. If you find any problems, you can raise your hand to the invigilator. Offer to replace. If the answer sheet is damaged or stained due to the candidate's personal reasons, it shall not be replaced.

2. During the process of answering questions, do not fold, soil or break the answer sheet. Otherwise, it may be misjudged and affect the candidate's score.

3 Do not answer, make drafts or scribble on the back of the answer sheet, and do not write other marks in other areas of the answer sheet, as this will not be an invalid test paper.

4. Once the bell rings at the end of the exam, candidates must stop answering papers immediately. Candidates can only leave the venue after the invigilator collects the papers and signs the admission ticket. Otherwise, the candidates are solely responsible for missing test papers.

The above are all the answers to how thick the pen should be for the civil service examination.
