I was failing Trigonometry in my senior year, left school at lunchtime, had two puffs of some sticky hash shit, fell out of my vehicle in the parking lot, went to class, requested 50 additional pages of paper requured to show my work, and got a perfect score. (Thing was, I never paid attention in that class and used simple formulas learned by grade 5 private school to view the problems and reverse engineer acceptable answers.
