Biology Stinks

I really have no idea what is going on in my biology class right now. We have a test tomorrow and I couldn't even tell you what it is over. I was absent one day and missed a whole lab about some kind of cycle that makes alcohol. I am completely lost in this chapter. I'm going to try to study the mark scheme and perhaps read the chapter out of the book tonight, but I'm not sure if that will help. I do not believe that I have any notes at all. I think instead of taking notes I either read my book for English or drew a picture of a sky and a rainbow. That class is the only one that I don't really pay attention in. It's just hard for me to concentrate when I have no idea what the teacher is talking about. Well I hope I can get prepared for this by tomorrow. It is going to take a whole lot of studying and I will probably be up until very early in the morning.
