Experimental classes in universities are a new training model for a specific major or department as a whole. As a pilot reform, Jiangsu Province has been exploring a new college entrance examination model for many years, which is suitable for all candidates in Jiangsu. The experimental class of extended materials has higher requirements for students, faster learning progress, and of course more opportunities to do some creative and research work. When these students graduate, most of them choose to continue their studies or study directly, and their general quality and ability are better than others.
