A college diploma is a prerequisite.
If you want to take the self-taught undergraduate course, you need to obtain a junior college diploma (or related certificate) first. This is a prerequisite for taking the self-study exam.
Academic certificates need to be obtained through exams.
Academic certificates can only be obtained by passing the exam, and you can't apply directly. If you want to take the self-study exam, please register in the study room of the local education bureau.
