Degree certificate (bachelor's certificate): It shows that you have a bachelor's degree.
Some colleges and universities can only issue diplomas, and only relatively powerful private undergraduate universities can issue bachelor's certificates.
1 If you are qualified to award a bachelor's degree when you graduate, but you don't get it, you can negotiate with the school leaders.
If you are not qualified to issue a bachelor's degree after graduation, but after a period of time, you can apply with the approval of the state (the state did not say that you can't reissue it after graduation).
If the school is not qualified to issue a bachelor's degree at present, you can't get it (but you can still get a master's degree and a postgraduate diploma).
