have 2 holiday on a week but

Tomorrow, I will have to come to the university because of an examination. I don't want to come because I have 2 reasons. First, usually, Saturday doesn't have all class. In spite of I must come, though tomorrow is a holiday, it's unwilling to come only this week. And, study hall on 14th building will close at 12 o'clock. I have to do some problems, studying for examinations and term paper. I won't be able to do those because I don't have PC in my house.
