Cheating?

I have a question. So say that you don't have enough time to read a story that was assigned for a class, is it wrong that I look on Sparknotes? I don't think so because I am actually doing work. I am making an effort. I read all that I could, but there is no way that I would be able to read the rest unless I pull an all nighter. So I am going to go with Sparknotes.
