This username reflects a self-deprecating yet motivational stance. In Chinese academic slang, 'Xuezha' refers to someone who does poorly in their studies. By saying 'I am a Xuezha if my grades are poor but I'm a Xueba (a studious person) when doing well,' the user expresses their hope for personal improvement or mocks at the academic pressure they may feel.
