Comprehensive high school classes in Hanjiang technical secondary school can take undergraduate courses. The probability of being admitted to the undergraduate course depends on the students' scores in the senior high school entrance examination (that is, the foundation of junior high school) and whether they can complete the corresponding learning tasks according to the teacher's requirements and achieve the corresponding learning goals in three years. Generally speaking, students with a score of 550 or above in the senior high school entrance examination (Yangzhou) are more likely to be admitted to the undergraduate course. Judging from the situation of this school this year, there are also students who scored below 500 points in the senior high school entrance examination that year, which is inseparable from the unremitting efforts of these students in the past three years.
