If you take an academic exam, it is impossible to get a certificate in one year. Generally, formal institutions will not promise to finish the exam in one year. The teacher also said that it would take one and a half years at the earliest. In the promotion of adult education, the examination time of self-taught examination is the fastest, and the examination time of self-taught examination is twice in some areas and three times in some areas, depending on the region. Self-taught exams are held in Guangdong three times a year, and you can apply for up to four subjects at a time. The minimum number of subjects for self-taught examination is eleven, and each exam is successfully passed, which is twelve. Moreover, self-taught undergraduate students need to write papers and graduation defense, not to mention applying for a diploma is not so fast. It usually takes several months to apply, so it takes one and a half years at the earliest, and you can't apply for a diploma in one year. I took the self-taught undergraduate course before, and the exam is already very fast. It takes a year and a half to complete, and I learned it from the teacher. If I teach myself, the time of the exam is not necessarily. There are many variables in the self-taught examination, and the graduation time of the self-taught examination cannot be guaranteed.
