Students in college preparatory classes mainly choose candidates who took the general college entrance examination that year and met the requirements of preparatory classes from ordinary colleges and universities for nationalities designated by the state. After reducing a certain score, you can select according to your own wishes. After one year's study in ethnic colleges or ordinary colleges, candidates will be directly promoted to the undergraduate or junior college of the school after passing the examination, and the school will organize its own preparatory graduation examination for professional distribution.

Although the preparatory class only supplements some key high school culture classes, its teaching purpose is completely different from other college entrance examination cram schools, and the content learned in teaching is also very different from the professional study in the future. The relevant departments shall, according to the basic requirements of preparatory teaching, organize the compilation of preparatory teaching materials in a unified way.

The introduction of competition mechanism has further strengthened the management of preparatory students. It is required to organize teaching and examination in accordance with the teaching plan, syllabus and teaching materials promulgated by the State Education Commission. It is stipulated that preparatory students who fail in Chinese, mathematics and foreign languages in the final exam will not be enrolled in universities all over the country.
