Exam anxiety

its rainy very hard outside, and i think it may be that way for the rest of the day. one of those days where i just would like to stay at home and do nothing. some people avoid school and think that the rain is a good excuse not to get out. well for me, i am totally opposite, i hate making up work and i just feel like school dont last forever. besides i have a major test that i would really like to have at least two more days to study for. if i tell you about it like saying its only twenty terms to know and only one group of sentences to write a paragraph on, you probably be like thats not bad. well that's the short version of it, the long version would be this. there are sixty terms but i only need to know twenty and there are four different categories of five to six questions to create an essay and i only need to really understand one, but the catch is, i dont know which ones, out of the terms or the essay questions, the professor will choose. but even if i got two more days to study i will still be in the same boat i'm in now, uneasy, i just dont want to take this kind of exam.
