If you leave school without going through the withdrawal procedures, you will be deemed to have dropped out of school automatically and may be recorded in the credit file. Because the number of places in the school is limited, you are admitted, but if you don't go, you will waste a place, resulting in candidates with lower scores than you not being admitted. According to different regulations in different provinces, candidates in this situation may need to have a letter of non-registration issued by the admission school when they take the college entrance examination in the second year. Seriously, it may affect you in two ways: 1. Your file, because it has been in school for half a year. If you don't go through the withdrawal procedure, your file will stay at school, and you should understand the consequences of losing it. Although it is mainly your high school and junior high school student status files, if you want to repeat, join the army, etc. Without documents, it will be affected. 2. It will affect your household registration. If your household registration has been transferred to the school and you have not gone through the formalities of leaving school, your household registration relationship will remain in the school. What do you want to do in the future? If you use an account, you may have to go to school to issue a certificate every time. And after a long time or more, your account may return to its original place, or it may be difficult to find it.
