How would you study for this and remember it for a quiz?

What you're doing is good,

make sure you are memorizing the things that you'd think would be on the test.

like so in so's friend's name was bob.

you dont need to know that unless his friend plays a HUGE roll in the book.

also pay attention to ALL DATES. and know what theyre about.

however,

if its something that is talked about in a paragraph or more, you might wanna make extra note of that.

Now idk what kind of learner you are,

but im better if i learn from my own experiences or funny things.

So relate the text to things in your life, or to things that are funny to you.
