The degree certificate has little influence on the examination compilation. You don't need a degree certificate to prepare for the exam, but you need a qualified academic certificate.

Take the establishment of teachers as an example. The teacher establishment only requires students with college education or above to apply for the exam. College education does not have a degree certificate, but they can still take the exam.

Generally speaking, preparing for the exam requires a full-time undergraduate degree or above. Some positions can apply for full-time college degree, and some positions can also apply for self-candidates, but it still depends on the recruitment requirements of each region.
