Ok, I sadly did none of those texts, so the only advice I can offer you is: LEARN THOSE QUOTES!
Seriously. Having lots of quotes in your essays-especially imbedded ones, (let me know if you don't know what those are)-are really important to your essays and teachers and examiners alike love it.
Another thing too-it helps if you read what other people have written about the texts. That way, you can magpie their ideas, and, if you've got a good memory, you could even try mentioning their name and quote them in your essays.
Don't be worried if you're a word or two out with the quote-you get some leeway with that. Plus, you'll only get better at learning them and using them the more you do it.
You could always ask your teacher for a list of good quotes? Or find websites online that have a list? Or even go through the texts yourself and pick the ones you think are best?
