Most universities will organize exams for basic subjects such as English and mathematics after the start of school, with the purpose of testing students' knowledge level, so as to carry out targeted training and improve basic knowledge.
Generally speaking, after the exam begins, a large number of freshmen will be divided into different grades, from high to low. At the same time, students of different levels have different teachers, but they learn differently. Generally, high-level students have basically mastered this kind of knowledge, and they only need to consolidate it a little before they can proceed to the next stage of professional study. Therefore, it is usually called an advanced class, and it is difficult to learn advanced mathematics or degree English. Middle-level students have mastered some knowledge in this field, but they are not deep and weak, which requires them to lay a solid foundation and improve their level. They are usually called advanced classes. Low-level classes are generally basic classes with incomplete knowledge, which needs to be greatly improved, and ordinary learning tasks will be more complicated.
The university also organizes exams to prepare students for their future professional study. When entering the university, freshmen's learning level will inevitably be uneven, and their learning methods and understanding ability are very different. Organizing open examinations to evaluate students in many aspects is helpful to discover their learning ability and teach students in accordance with their aptitude. Many universities will arrange less such courses (basic subjects such as mathematics and English) for high-level students, so that some students can transfer to other majors for further study. Low-level students will be given more basic courses, strengthened training, and gradually upgraded to high level.
The arrangement of entrance examination is also to promote the all-round development of students. Many students are seriously biased when they start school, which will greatly affect their professional study, and it is more likely to affect their graduation. The purpose of universities is to train more excellent and all-round professionals. Doing a good job in undergraduate education and laying a good foundation will be of great benefit to future study and career.
