You can transfer. Isn't the school notified every year? General majors can be transferred. I only know that it seems that Jiangsu candidates can't transfer to architecture, but everything else can, except that the policy changes every year. This year's transfer registration should have ended.

The application requirement seems to be that you have not failed the course, then take the exam and be admitted according to the ranking.

Notice will be issued in May and June every year, and the exam will be transferred in August.
