Hello, I suggest you only fill in Band 6. Practice experience suggests that those who don't have relevant certificates should not fill in it, because at present we are all trying to show ourselves better, but during the online qualification review, the reviewing teacher doesn't have much time to read our information in detail, but once we get a good written test score and are shortlisted for the interview, the additional information we fill in will bring us a lot of trouble, hoping to help you ~
