How does David Copperfield behave after the first bitter experience at Salem House?

Salem House is an absolute nightmare for David. It's more like a prison camp than a school, run by the cruel, sadistic Mr. Creakle, who's been instructed by Mr. Murdstone to beat David as often as possible. David's been marked quite literally as a violent troublemaker, a biter no less—he's forced to wear a placard round his neck which reads "Take care of him. He bites."—and so his cards are well and truly marked before he sets foot in this terrible place.
Nonetheless, David tries to keep his head down and study, which he does thanks to the encouragement of the kindly Mr. Mell. Mell is chronically underpaid and overworked, yet somehow he's able to provide David with a few crumbs of knowledge, which is more than can be said of the violent, psychopathic Mr. Creakle.
During his first term at Salem House, David also makes friends quite easily—though one of his friends, the rich and ill-disciplined Steerforth, turns out to be a very false friend indeed.
