The signature of the filer means that the filer confirms the contents filled in and then signs the signature for confirmation. That is, after the candidates submit their volunteers, the school will print out your volunteers and let you sign for confirmation. First of all, you have to understand that as long as you submit it voluntarily, you can't change it whether you sign it or not. The advantage of the examinee's signature confirmation is that the confirmation form is the only legal evidence to fill in the volunteer. If the admission result is inconsistent with the confirmation form, you can claim your rights by signing the confirmation form.
