Okay, I didn't think that far
Were you smarter than most, but got mediocre grades for not caring about something as stupid as grades?
Did you have a strong, but controversial sense of justice?
Do you think analytically, using logic instead of feelings when making an argument?
Were you more mature than your peers?
If so, it's probably Light Yagami.
Light was literally a genius who was the top student in the country and so no anon will ever come close to him.
Even if he half assed school, he would still get into a top university just based on his IQ. Comparing any of us to him is stupid.
