In English:

The Graduation Certificate and Degree Certificate are two distinct documents that represent different aspects of a student's completion of their university studies.

The Graduation Certificate is a document that verifies that a student has fulfilled all the course requirements of their respective institution and has met the graduation standards. It typically includes the student's personal information, the degree or major obtained, the duration of study, as well as the school's seal and signature. The Graduation Certificate serves as an official document attesting to the successful completion of the student's program.

The Degree Certificate, on the other hand, is a document that confirms that a student has been awarded a specific academic degree, such as a Bachelor's degree, Master's degree, or Doctorate degree. The Degree Certificate generally includes the student's personal information, the type of degree, the field of study, the name of the university or institution conferring the degree, as well as relevant seals and signatures. The Degree Certificate serves as an official document verifying that the student has achieved a specific academic qualification.

In summary, the Graduation Certificate verifies the completion of all course requirements and meeting the graduation standards, while the Degree Certificate further confirms the attainment of a specific academic degree.
