All the names, test numbers and other information on the answer sheet are just additional reference information.

When the machine scans the test paper, it directly reads the test number information on the bar code as the basis for marking and grading.

The information you write will only be used as the basis for verification in case of dispute, that is, even if you don't fill in your name and test number, as long as the barcode is not mislabeled, there is no problem.
