After you get a bachelor's Degree and go to study an advanced Certificate, Master's Degree, or Doctoral Degree we Called "Graduate Study"
------------------------------------------------------
By nature, graduate courses (advanced certificates, master's degrees, and doctoral degrees) have several overlapping bodies of knowledge. Only a few courses are specialized and focused on learning in a way that aims to produce advanced academic leaders who are experts in the field. Master's degrees and doctoral degrees both aim to make academic leaders but differ in the research to create knowledge; Master's degrees emphasize learning the research process and applying the research process to develop future work, while doctoral degrees emphasize creating new knowledge or creating innovative prototypes in a field of study.
---------
From the above concepts, many American universities emphasize studying in a master's degree program along with a doctorate. As soon as you apply for a doctorate program, the content and activities are mostly studied together with the master's degree. The difference is the thesis, which emphasizes the creation of new knowledge in the field of study. If you apply for a doctoral program, study for 5-6 years still do not graduate, and decide not to continue studying, you will not get anything ( some universities have equated your experience of learning and give you a master's degree before coming back to your country).
