A two-cent miscellaneous about my background: Before my undergrad, I was a Mathematics specialized student in high school with multiple experiences (but without positive records) in Math competitions, with a notable record (sadly) of being the highest score without a prize in the VMO 2019.
I view my experience (and especially the failures) in Competitive Mathematics as one of the main motivations for my theoretical interest in graduate studies.
Besides, during my secondary education (grade 6 to grade 9 in Vietnam), I spent half my time learning Social Science (mostly Literature and Geography), before focusing on Mathematics in high school.
