Busy, Busy, Busy!

I've been working on my senior thesis in English for months, and the dead line is next Thursday. However, I have to write 8 more pages because the number of words are much less than that of required. At least 9,000 words are necessary for a thesis in English, but my paper has still around 7000 words. If I failed to present it by the dead line, my graduation will be extended until September. As I don't want miss any class at college, I am in a dilenma whether to attend today's classes. If I attended the classes, I cound not write my papaer. If I wrote my paper, I could not attend the classes. What should I do???
