1. Contact the local college entrance examination office in time and ask them to re-sign the college entrance examination confirmation form.

2. The college entrance examination office can't re-sign the college entrance examination physical examination confirmation form, but it can apply to the local education department and ask them to issue a new college entrance examination physical examination confirmation form and sign it for confirmation.
