She goes to her maths class and the teacher asks 'calculate the number of points of intersection between the parabola y=2x squared-x+1 and the line 2y+6x=1'. She gets sooo totally blown away by the question (as she had'nt been studying) that all she can do is scratch her head. Next thing you know, she gets sucked into a powerful portal of misty purple energy that turns all living things to stone. And thats why you should study at least 15 hours a day!
