The learning process of lottery players in Beijing is staged. Different students can attend classes at different stages. The learning process of their school includes four stages: primary, intermediate, advanced and comprehensive. At each stage, they must be promoted to the class. Only by passing the exam can they be promoted. If they fail, they must continue to study in this class until they learn well. At that time, teachers were very strict and demanded a lot of students' study. I feel that I can't stand it anymore. It's so difficult to learn, and I always can't achieve the desired effect. But it is also such a teaching mode, which is strict with us, so that I can graduate and work outside, and all kinds of makeup styles are comfortable. So the teacher is strict, which actually helps us a lot.
