pretty sure that izaya was a great student who scored near perfect, or perfect on most of his exams and tests. on occasion he would miss a homework assignment, but other than that he was one of the top students in the class. but he never helped anyone with their work, even if they asked, because it wasn’t his problem— he had other things to do e.g. running around (literally) and ruining lives
also i’m sure that if izaya tried to “bullshit an essay” he’d still get a fantastic grade on it. he’s just… good.. at things.
