Answering tools: black pen or signature pen, eraser, 2B pencil, pencil sharpener. Pencils and pens/pens are recommended to be kept in reserve. Put away the pencils sharpened before the exam to prevent the nib from breaking, or directly use the special pens for the exam currently on the market.
Other answering aids: ruler and protractor. Rulers and protractors can sometimes play a certain role in solving problems in line measurement.
In addition, it is suggested that candidates must debug their watches during the exam, because they may not grasp the time during the exam and application, so candidates must wear their watches and answer.
