dropping/withdrawing from a class

hey gang I hate this class so much I've missed an exam and a bunch of classes due to illness and now I have a group presentation on Thursday and I don't even have their contact info so I can't be involved in said group project... the prof wants us to read a really long book before that day and I haven't even started it. I am dying to drop this class, is it still even possible? any help is appreciated thank you so much!
