I recommend "Baitai Education" of Bagua No.2 Road, a professional self-taught student aid unit. It has a good reputation in Shenzhen, where my wife also studies. In two years, all the undergraduate diplomas and degree certificates were obtained.
Self-taught exams are divided into big exam classes and small exam classes. Generally, everyone takes part in the big exam class and has two exam opportunities every year, mainly for self-study. If you have strong self-study ability and the economy is not very loose, it is recommended to take the big exam, but it will take a relatively long time to get the diploma.
However, most quiz classes are jointly organized by school-running institutions and examiner colleges, or directly organized by examiner colleges. Teachers from examiner colleges and training institutions give lectures on weekends and evenings, and there are four exam opportunities every year. The advantage is that there are many exam opportunities, and the time and pass rate of the teachers in the examiner's college are guaranteed, but the tuition fee is about 3000-5000 per semester, which is relatively expensive.
Personally, I took part in the quiz class and took classes directly in the classroom of the examiner's university every night, which gave me a learning atmosphere of going to college. On the basis of the school schedule, I took two more courses each semester, and it took me a year and a half to get my undergraduate diploma and bachelor's degree. Time is still quite fast. It cost more than 10,000 points, and I can accept it economically.
In addition, you'd better choose your professional examiner college, preferably from your city, which will be much more convenient, including finally getting a degree certificate.
