Why does she do nothing in class and complain that she doesn't understand?

There's a girl who sits near me in my college class who doesn't do anything except use her phone or sleep, when the professor is lecturing. Then when it's time to take a quiz in class, she's always the first one to complain that she "doesn't remember a single thing taught and the prof is throwing too much work at us."
