You've got plenty of time, if you want to accept failure then that would be the only reason you fail come exam time. Put more hours in and improvise with your notes if you're going too slowly. Compare your situation to others, I was talking to a person who missed the past few months of their degree and will be undertaking their finals, that's a lot of work too but they're committed. Honestly, if the notes thing is getting you down, ditch them and revise straight from the book.
