Hello, if there are mistakes in the grades uploaded to Xuexin.com's database, you can correct them, but it must be corrected by the transferred school. The procedure is to find the class teacher and the academic affairs office of the school to correct, provide their own real grades and relevant certificates, and ask the school to upload the data again. Only after the education department re-examines the data can the information be changed on Xue Xin's website. Website personnel have no right to modify any data. The above reply is for reference only.
