ONe flew over the Cuckoo's nest question!?

I didn't finish part one yet, but i have to read it for my honors lit class next year over the summer for my sophmore year. I don't really understand what is going on, i just past the part where McMurphy came and they are separating accutes and chronics. Spark notes kind of helped, i might not understand it because it is boring or will it become easier to understand as i read. I find it hard to pay attention to it though because i find it so uninteresting so far which may be why i dont understand what is going on!
