Gonna give you a few things that I used
Microcosm, the examiner loves you to use that word when you can put it into context! The ranch is a microcosm for the real world due to Candy representing such and such. It is a really nice ender to an essay!
Crooks lives in the harness shack or whatever, it is shown to be holder black men and women down.
Curly's wife is always wearing red and never enters the rooms where she is talking except for the barn. The red shows a colour of violence, of blood, or aggressiveness. She never enters because she is not wanted, women cause to much trouble in a man's worl of ranching. The only person she can relate to is Lenny because he is useless unless told what to do, and he doesn't have the intelligence to run away from trouble
Just a few points I just thought of, I did it last year so have fun! The best thing I can tell you is that make sure you add context!!!! Once you quote from the book make sure you break it down into smaller quotes and analysis the smaller quotes.
