Secondary school students can take the college entrance examination before taking the undergraduate course, but it takes less time to get an undergraduate degree by studying undergraduate course. Undergraduate course means that candidates apply for self-taught undergraduate courses at the same time, and only need to get the diploma of the specialized courses before graduating from the self-taught undergraduate courses.

Adult junior college+self-taught undergraduate course: this is the most commonly used combination at present. The exam in adult university is very simple. As long as you pass the entrance exam, you can basically pass the later studies and exams easily, so candidates don't have to worry too much. Just focus on the self-taught undergraduate course.
