There are no thresholds and restrictions for self-study exams, but you need to study by yourself, take exams in examiner colleges, complete all subjects and complete credits before you can apply for graduation. Classes are relatively free, and learning can be arranged according to your own time. Suitable for self-study exams while working. In addition, the current self-taught examination is comparable to the proportion of unified recruitment in social awareness and gold content, and most of the subjects studied by self-taught examination are popular jobs in society, so I studied.
Generally speaking, if the unified recruitment fails, the only thing that can improve academic qualifications and has high gold content is the self-study exam.
hope this helps
