What does the shift system mean? The shift system was put forward by the Ministry of Education in the "Opinions on Implementing the Enrollment System" of the current education reform. In the future, high school students can also be included in the total score of the university. No longer divide arts and sciences.
So your child is good at history and physics, and can be included in the college entrance examination results at the same time. Then there is the usual study problem, and the children in each class are not fixed. People who love science can attend classes with people who love liberal arts. For example, today's history class, you and I both go to classroom A, but tomorrow's physics class in classroom B, you can go with another person.
Work is not fixed. Everyone is fixed. Those people have classes.
What do you mean by regular classes?
That is to say, the people in the class are fixed, not mixed, for example, students of different grades and grades in an elective course in a university are temporarily together.
Class is the basic unit of a school, and class teaching is the most representative form of education in modern times. A class is usually composed of one or several teachers and a group of students, and the educational function of the whole school is mainly realized in class activities.
Class is an educational organization established by the school to achieve certain educational goals. It is students of the same age and roughly the same educational level according to a certain number of people. Class is not only a resource for students to receive knowledge education, but also a resource for students' socialization and self-education.
