If you want to learn English well, you don't care about your diploma. You might as well go to an English training class. If you really want to go to the English department of night school, many schools have it, such as Nantah, Southeast University, Nanjing Radio and TV University and so on. But you have to take the adult college entrance examination at night school. After you pass the exam, you will be promoted to college for three years and to secondary school for five years. An English teacher from Nantah Night School told us that in college, you can't learn English well in two hours' class. Only by spending two hours a day watching, learning and speaking English by yourself, and persisting for a long time, can we learn English well. Moreover, she said that if we want to get an English diploma for the postgraduate entrance examination as soon as possible, we are not advised to apply to Nantah, saying that it is too difficult to take the exam, but it is hard. If you really want to apply for an English major at night school, go online and search for amateur majors in various schools. Every school is different, and even a school's major will be different every year. You can only sign up for the adult college entrance examination after choosing a major.
Also, amateur schools are divided into correspondence, evening classes and full-time full-time study. Night school is a kind of amateur study, and classes are held at night or on weekends. If you are not a student, you cannot apply for CET-4.6. It is an adult bachelor's degree in English major. A few years ago, it was relatively simple, equivalent to CET-3 to CET-3.5. But in recent years, it has become more and more difficult to take the exam, and it is a bit difficult to go to Band 4. As for whether full-time full-time study is a student, I don't know if I can take CET-4 or CET-6. I have to consult.
