Excuse me, can double non-graduate students pass the application examination if they have applied for sci three-zone papers?
The key is that you plan to be a doctoral student majoring in pure mathematics, which requires a higher theoretical level. Generally, a master's degree is about application rather than theory. It seems a little difficult for you to study for a master's degree. I suggest you directly contact the tutor you want to apply for and send your research paper to the tutor for direct reading.
