Art class isn't going well—it's hard to do figure drawing when your figure is in a head-to-toe burka. Where are Bob Ross and his happy trees when you need them?
They eventually get to draw men, whose limbs are at least distinguishable.
However, Marjane gets in trouble for looking at a male model. She asks, "Should I draw this man while looking at the door?" (35.12), and the person reprimanding her actually says yes.
This absurdity just makes Marjane more and more rebellious. Eventually her attitude alienates half of her class.
"There was still the other half" (35.33), she says, and this other half starts meeting outside of school to draw each other without robes.
They also start throwing secret parties, much like Marjane's parents used to go to when she was was a girl.
One night, they are raided and a friend named Farzad flees. He tries to jump from one building's roof to another, and he falls to his death.
The friends are shaken, and many stop partying altogether. But Marjane knows that this is what the regime wants—to end partying—so she just parties harder, like Andrew W.K.
