If you haven't finished a course, complete it or complete credits, you will get a certificate of completion when you graduate. After graduation, if you complete the course and pass the exam, you can apply for a replacement diploma. This is the certificate of completion that the school will take back.

If you haven't graduated and can't continue your studies for some reason, get an associate degree certificate.

The reissued diploma is the same as that of ordinary graduates, except that the graduation time is the time to get the diploma, not the time to complete the certificate.

Certificate of completion refers to that students fail in school, fail to reach graduation qualification, or their learning institutions cannot issue certificates recognized by national or regional educational institutions, or they should not or cannot issue graduation certificates according to national regulations.

"Drop-out" means that students with school status drop out of school before completing the courses stipulated in the education plan (except those who are expelled from school); It can also refer to those who have completed the course study and compulsory links, with qualified grades, but have not completed their graduation thesis (including those who have not defended their graduation thesis).
