Diary: Studied! I think I am well prepared but I am still scared!

I did study in my office for the whole day as usual. But Brian, Kiomi and Kumudo came to my office today and asked me many questions. I tried my best to teach them. Anyway, I studied until 12:30am and I just got home. I think I am well prepared but I am still scared since it is my last chance to take exam. If I blow it, I am out of school right away and they have no mercy to me. In fact, the math dept kicked out 60% of the phD students. Well, there is another thing that I also worry now. I may not be able to get up on time tomorrow to take the exam at 9am. I have been sleeping very late at about 4am in the morning. I hope Brian and Kiomi call me tomorrow and wake me up.
