Contact the class teacher. The class teacher has the right to revise, so you should contact the teacher as soon as possible, and don't delay the normal registration. If there are special circumstances, you should contact the local examination center as soon as possible to find a correct and reliable way to make corrections to ensure that the child's registration is completed on schedule. As the first level of the senior high school entrance examination, parents must conscientiously implement each item, and don't lose big because of small.
