Blind trial is not a form. We also sent it out this year. There are two blind tests. One is that there is no tutor name, and the other is that there is a tutor name. Those without a tutor's name are usually much stricter than those with a tutor's name. Generally, it is sent to other schools for review, such as China Southern Airlines to Beihang University, Beihang University to Xigong University and so on.
