If you major in school, it may be different every year. You can check it on the website. Different majors may be in different teaching points. Classes generally follow: Monday to Friday, one night (18:00 to 20:30), and a whole day on weekends; The most important thing is to see how the major is arranged; As for chaos, this,,, can only say that each class is different and has something to do with the teacher. The overall teaching atmosphere is still there. However, adult education is always different from the education of students in school. Your attitude is the most important! ,,,, Good luck.
