This undergraduate course is like this. The junior college is a diploma in adult education, that is, the adult college entrance examination, and the undergraduate course is a self-taught exam. At least three years. So it's not a full-time college. The undergraduate course is a full-time junior college and upgraded to a full-time undergraduate course. This is really difficult. Whether the self-study exam is useful depends on you, whether your chosen major is popular or not, and whether it is easy to find a job. Self-taught countries recognize academic qualifications. However, the specific treatment in all aspects is unknown. If you can get into those full-time schools. Don't read the self-study exam.
